Add headers to enable CryptoCell integration ...

This patch adds header files with required declarations and
macro definitions to enable integration with CryptoCell SBROM
version `CC712 – Release 1.0.0.1061`. These headers enable ARM
Trusted Firmware to build and link with CryptoCell SBROM
library.

Add support for RSASSAPSS algorithm in mbedtls crypto driver ...

This patch adds support for RSASSA-PSS Signature Algorithm for
X509 certificates in mbedtls crypto driver. Now the driver supports
RSA PKCS2_1 standard as mandated by TBBR.

NOTE: With this patch, the PKCS1_5 standard compliant RSA signature
is deprecated.

Add ufs stack and designware phy

drivers: add ufs stack ...

If UFS device is initialized, we could just make it out of
hibernation by UFS_FLAGS_SKIPINIT. And vendor's dirver is always
focus on PHY setting. We could use UFS driver directly if it
exits from hibernation.

There're eight LUNs in UFS device. The UFS driver only provides
the read/write API with LUN. User could define his own read/write
since user may want to access different LUNs.

mbedtls: Use `tf_snprintf` instead of `snprintf` ...

The Trusted Firmware uses a subset of the APIs provided by mbed TLS.
This subset internally uses `snprintf`, but the only format specifier
used is '%d', which is supported by `tf_snprintf`.

This patch makes mbed TLS use `tf_snprintf` instead of `snprintf`,
saving 3 KB in both debug and release builds when TBBR is enabled.

mbedtls: Namespace for TF specific macros ...

An earlier patch (arm-trusted-firmware#874) migrated MBEDTLS_ suffixed
macros to have a TBBR_ suffix to avoid any potential clash with future
mbedtls macros.

But on reflection the TBBR_ suffix could be confusing as the macros
are used to drive TF-specific configuration of mbedtls. As such
this patch migrates these macros from TBBR_suffix to TF_MBEDTLS_
suffix which more accurately conveys their use.

mbedtls: Namespace TF specific macros ...

These macros are not part of mbed TLS so they should not be prefixed

`TBBR_` suffix to highlight that they only used in TF.

`MBEDTLS_KEY_ALG` was not modified because that is documented and used
by platforms to select the key algorithm.

uart: 16550: Fix getc ...

tbz check for RDR status is to check for a bit being zero.
Unfortunately, we are using a mask rather than the bit position.

Further as per http://www.ti.com/lit/ds/symlink/pc16550d.pdf (page 17),
LSR register bit 0 is Data ready status (RDR), not bit position 2.

Update the same to match the specification.

GIC driver changes for extended power management

GICv3: Introduce power management APIs for Redistributor ...

Some GICv3 implementations have provision for power management
operations at Redistributor level. This patch introduces and provides
place-holders for Redistributor power management. The default
implementations are empty stubs, but are weakly bound so as to enable
implementation-specific drivers to override them.

emmc/sd: for C99 compliance, changed the unsigned char/short bitfield to unsigned int bitfields ...

C99 restricts bitfields type is signed and unsigned integer or _Bool.
See section 6.7.2.1 Structure and union specifiers.
"A bit-field shall have a type that is a qualified or unqualified version
 of _Bool, signed int, unsigned int, or some other implementation-defined type."

Since the compiler packs bitfields anyways, actual data layout in the structure is unaffected.

emmc: support CMD23 ...

Support CMD23. When CMD23 is used, CMD12 could be avoided.

Two scenarios:
1. CMD17 for single block, CMD18 + CMD12 for multiple blocks.
2. CMD23 + CMD18 for both single block and multiple blocks.

The emmc_init() should initialize whether CMD23 is supported
or not.

GICv3: Fix the GICD_IROUTER offset ...

This patch fixes the offset of GICD_IROUTER register defined in gicv3.h.
Although the GICv3 documention mentions that the offset for this register
is 0x6100-0x7FD8, the offset calculation for an interrupt id `n` is :

   0x6000 + 8n, where n >= 32

This requires the offset for GICD_IROUTER to be defined as 0x6000.

Fixes ARM-software/tf-issues#410

Rework type usage in Trusted Firmware ...

This patch reworks type usage in generic code, drivers and ARM platform files
to make it more portable. The major changes done with respect to
type usage are as listed below:

* Use uintptr_t for storing address instead of uint64_t or unsigned long.
* Review usage of unsigned long as it can no longer be assumed to be 64 bit.
* Use u_register_t for register values whose width varies depending on
  whether AArch64 or AArch32.
* Use generic C types where-ever possible.

In addition to the above changes, this patch also modifies format specifiers
in print invocations so that they are AArch64/AArch32 agnostic. Only files
related to upcoming feature development have been reworked.

CCN: Add API to query the PART0 ID from CCN ...

This patch adds the API `ccn_get_part0_id` to query the PART0 ID from the
PERIPHERAL_ID 0 register in the CCN driver. This ID allows to distinguish
the variant of CCN present on the system and possibly enable dynamic
configuration of the IP based on the variant. Also added an assert in
`ccn_master_to_rn_id_map()` to ensure that the master map bitfield provided
by the platform is within the expected interface id.
