No need to process fit image during resume.
All needed parts are already available in DRAM.

Changes in v3:
- At resume, R5 SPL doesn't restore TF-A anymore.
TF-A is started like during a cold boot. R5 SPL will notify that the board is
resuming using a magic value written in the scratchpad ram.
TF-A will restore itself.

Add the exit retention support.
The enter retention is done by DM-Firmware.
A part of the exit retention sequence is specific to the board.
It is done in board_k3_ddrss_lpddr4_release_retention.

Add the capability to detect a resume.
To detect the resume, SPL searches a magic value (0xBA) in a register
of PMICA.
This value is set by DM-Firmware during the suspend sequence.

Add test_enter_suspend command using PSCI.
This command is only to test suspend sequence from U-Boot.
