The RPMhPD setup on SA8155P is different compared to SM8150. Correct it to ensure the platform will not try accessing forbidden/missing RPMh entries at boot, as a bad vote will hang the machine.

* SA8155P is an automotive variant of SM8150, with some minor changes.
|
|
* Most notably, the RPMhPD setup differs: MMCX and LCX/LMX rails are gone,
|
|
* though the cmd-db doesn't reflect that and access attemps result in a bite.
