msm: ocmem: Serialize allocation requests only when necessary

Certain clients of ocmem always have exclusive regions set aside in
the OCMEM memory map. Allocation requests for such clients do not
have to wait for any pending evictions in progress to be completed
nor will trigger any new evictions and can be safely scheduled right
away.

msm: ocmem: Do not use data mover for clearing ocmem memory

In the non secure environment the data mover is used to clear
the ocmem memory. The ocmem driver no longer uses the data
mover for this operation.

ARM: dts: msm: Remove dual configuration for CPU on msm8974

Remove the dual configuration for CPU master on msm8974. The original
intent of this feature was to overcome some bus limitations in certain
usecases. However new desgin impovements have made this feature requirement
obsolete.

msm: peripheral-loader: Change IOMAP_SIZE from SZ_4M to SZ_1M

The ioremap call made for zeroing out trailing memory is currently
requesting for a 4M memory region. This is resulting in vmalloc
allocation failures on some platforms.
Instead, request for 1M memory locations and zero out the area
in smaller chunks to make this failure less probable.

Revert "mm/pagewalk.c: walk_page_range should avoid VM_PFNMAP areas"

This reverts 7244c108264b441a703f5b446d17a627da50af00 as it
caused crazy memory corruption.
