Tf2.0 tegra downstream rebase 1.7.19

Updates for STM32MP1

This patch cleans the Memory controller's interrupt status
register, before exiting to the non-secure world during
cold boot. This is required as we observed that the MC's
arbitration bit is set before exiting the secure world.

This patch updates the plat_my_core_pos() and platform_get_core_pos() helper
functions to use the `PLATFORM_MAX_CPUS_PER_CLUSTER` macro to calculate the
core position.

core_pos = CoreId + (ClusterId * PLATFORM_MAX_CPUS_PER_CLUSTER)

This patch moves the TZDRAM base address to SCRATCH55_LO due
to security concerns. The HI and LO address bits are packed
into SCRATCH55_LO for the warmboot firmware to restore.
SCRATCH54_HI is still being used for backward compatibility,
but would be removed eventually.

The scratch registers are populated as:
* RSV55_0 = CFG1[12:0] | CFG0[31:20]
* RSV55_1 = CFG3[1:0]
* RSV54_1 = CFG1[12:0]

The non secure world would like to profile the boot path for
the EL3 and S-EL1 firmwares. To allow it to do that, a non-secure
DRAM region (4K) is allocated and the base address is passed to
the EL3 firmware.

This patch adds a library to allow the platform code to store the
tag:timestamp pair to the shared memory. The tegra platform code
then uses the `record` method to add timestamps.

MISRA Rule 10.3, the value of an expression shall not be assigned to
an object with a narrower essential type or of a different essential
type category.

The essential type of a enum member is anonymous enum, the enum member
should be casted to the right type when using it.

Both UL and ULL suffix equal to uint64_t constant in compiler
aarch64-linux-gnu-gcc, to avoid confusing, only keep U and ULL suffix
in platform code. So in some case, cast a constant to uint32_t is
necessary.

This patch saves the TZSRAM context and takes the SoC into System Suspend
from the "_wfi" handler. This helps us save the entire CPU context from
the TZSRAM, before entering System Suspend. In the previous implementation
we missed saving some part of the state machine context leading to an assert
on System Suspend exit.
