msm: kgsl: Add LLC support for A608 GPU

For A608 GPU, SCID configuration registers have moved from CX_MISC
to GBIF register space. And the GPU HTW SCID is configured via
NoC override in XBL image.

And, LLC page attributes override through GBIF is not supported
with MMU-500. Skip this override setting for A608 which
has the GBIF and MMU-500.

Also, use DOMAIN_ATTR_USE_LLC_NWA attribute for GPU traffic and
page table walk to be read-allocate, write-no-allocate.
