marvell: Migrate to new interfaces ...

- Migrate to bl2_early_platform_setup2().
- Remove references to removed build options.
- Use private definition of bl31_params_t.

This is an incomplete migration, the platform doesn't currently compile.

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.

Readjust BL2 size after sharing Mbed TLS heap ...

After introducing the Mbed TLS shared heap optimisation, reducing BL2

Mbed TLS shared heap

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.

plat: a8k: enable PMU overflow interrupt handler ...

This patch enables handling PMU overflow IRQ by GIC SPI's
directly in EL3. Also implement additional SMC routine,
which can disable the solution on demand in runtime.

Since it is possible to configure PMU interrupt trigger type
in the MADT ACPI table, it is enough to set it only once in EL3
during initialization.

Rename a8k_common.h to armada_common.h to keep the same header

This is especially useful since various Marvell platforms may

and the per cpu stack memory, thus the need to redefine stack base
pointer for these platforms. This patch allows each board in ARM
