Remove deprecated interfaces for all platforms

mmc: Update framework to use standard response type ...

Respect official response type and update response to follow
official specification.
All the MMC_RESPONSE_R(_x) are replaced with each corresponding define.

Partly revert 2a82a9c for dw_mmc.c:
Responses R1, R1B and R5 have CRC.

juno: Revert FWU update detect mechanism

juno: Revert FWU update detect mechanism ...

The patch 7b56928 unified the FWU mechanism on FVP and Juno
platforms due to issues with MCC firmware not preserving the
NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
writing to the NOR flash while executing from the same flash
in Bypass mode had some stability issues. Hence, since the
MCC firmware issue is resolved, this patch reverts to the
NVFLAGS mechanism to detect FWU. Also, with the introduction
of SDS (Shared Data Structure) by the SCP, the reset syndrome
needs to queried from the appropriate SDS field.

The Marvell A8K SoCs use the MI2CV IP core from Mentor Graphics, which
is also used by Allwinner.

As Mentor Graphics allows a lot of customization, the MI2CV in the two
SoC families are not compatible, and driver modifications are needed.

Extract the common code to a MI2CV driver.

Mbed TLS shared heap

cpus: denver: Implement static workaround for CVE-2018-3639 ...

For Denver CPUs, this approach enables the mitigation during EL3
initialization, following every PE reset. No mechanism is provided to
disable the mitigation at runtime.

This approach permanently mitigates the EL3 software stack only. Other
software components are responsible to enable it for their exception
levels.

TF-A implements this approach for the Denver CPUs with DENVER_MIDR_PN3
and earlier:

*   By setting bit 11 (Disable speculative store buffering) of
    `ACTLR_EL3`

*   By setting bit 9 (Disable speculative memory disambiguation) of
    `ACTLR_EL3`

TF-A implements this approach for the Denver CPUs with DENVER_MIDR_PN4
and later:

*   By setting bit 18 (Disable speculative store buffering) of
    `ACTLR_EL3`

*   By setting bit 17 (Disable speculative memory disambiguation) of
    `ACTLR_EL3`

Reduce BL2 size for FVP ...

This patch reduces BL2 size by 12kB. Thanks to the shared Mbed TLS heap
between BL1 and BL2, BL2 now requires less memory since it doesn't need
to allocate a heap anymore.

Support shared Mbed TLS heap for FVP ...

This patch introduces the shared Mbed TLS heap optimisation for Arm
platforms. The objective is the Mbed TLS heap to be shared between BL1
and BL2 so as to not allocate the heap memory twice. To achieve that,
the patch introduces all the necessary helpers for implementing this
optimisation. It also applies it for FVP.

Prepare Mbed TLS drivers for shared heap ...

The Mbed TLS drivers, in order to work, need a heap for internal usage.
This heap, instead of being directly referenced by the drivers, now it
is being accessed indirectly through a pointer. Also, the heap, instead
of being part of the drivers, now it is being received through the
plat_get_mbedtls_heap() function. This function requests a heap from the
current BL image which utilises the Mbed TLS drivers.

Those changes create the opportunity for the Mbed TLS heap to be shared
among different images, thus saving memory. A default heap
implementation is provided but it can be overridden by a platform
specific, optimised implemenetation.
