occ: Add support to read V2 format of OCC-OPAL shared memory region
Add support to read OCC-OPAL shared memory region version2 to parse
ultra-turbo pstates and core-to-max-pstate-allowed array and append
it to device tree. Each element of core-to-max-pstate-allowed indicates
the maximum pstate sustained with 'n' online cores.
