Optimize the UBWC-P driver for power by ensuring that UBWC-P is only
powered up when there is a non-linear UBWC-P buffer allocated.
Optimize the performance of the memory offlining by
adding support for the CMO component to be interrupted by the
allocation of a new UBWC-P buffer.

This reverts commit ff2498ad42.
No longer needed now that we are doing CMOs with an
un-cached mapping.

- Program height in bytes for non-v1 hardware
- Additional error checking at various places
to prevent regulator call with NULL vdd
- Set_ops fails when we do rmmod and then insmod
ignore the return value so we can successfully insmod
This is a hack that needs to be removed for final product
