msm: ocmem: Turn ON the memory macros in Normal Pass through mode

Currently the default ON state for the OCMEM memory macros is to force
the core and peripheral logic to remain ON. Change this to Normal
Pass-through mode which allows the upstream sleep controller to decide
the actual power state of the macros.
