Li Fei1 80121b8347 hv: pSRAM: add pSRAM initialization codes ...

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
