The added parse_ptct function will parse native ACPI PTCT table to
acquire information like pSRAM location/size/level and PTCM location,
and save them.

1.We added a function init_psram to initialize pSRAM as well as some definitions.
Both AP and BSP shall call init_psram to make sure pSRAM is initialized, which is
required by PTCM.
BSP:
To parse PTCT and find the entry of PTCM command function, then call PTCM ABI.
AP:
Wait until BSP has done the parsing work, then call the PTCM ABI.
Synchronization of AP and BSP is ensured, both inside and outside PTCM.
2. Added calls of init_psram in init_pcpu_post to initialize pSRAM in HV booting phase
