msm: ocmem: Add a separate Kconfig for keeping clocks enabled. 

For bringup purposes add a new Kconfig item that performs
the extra vote for the ocmem core clock and thus forcing the
core to remain turned ON at all times.

The previously used Kconfig MSM_OCMEM_POWER_DISABLE for the
same purpose now skips all power operations including clock votes.

Always vote for all OCMEM clocks and keep all OCMEM

Both local power management and RPM assisted power modes

Disable all OCMEM power management.
This keeps all OCMEM macros turned ON at all times thus
never allowing them to be turned OFF. Both local power
management and RPM assisted power modes are supported.
Skip all OCMEM power operations that turn ON or
turn OFF the macros. Both local power management and
RPM assisted power management operations are skipped.
Enable this configuration if OCMEM is being exclusively
used as GMEM or OCIMEM.
