This patch enables the 'WARMBOOT_ENABLE_DCACHE_EARLY' flag to enable D-cache early, during the CPU warmboot sequence. This flag is applicable for platforms like Tegra, which do not require interconnect programming to enable cache coherency.

Tegra: lib: library for profiling the cold boot path
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.

Tegra: fix defects flagged by MISRA Rule 10.3
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.
