drm: msm: a6xx: Add support for A618
This patch adds support for enabling Graphics Bus Interface(GBIF) used in multiple A6xx series chipets. Also makes changes to the PDC/RSC sequencing specifically required for A618. This is needed for proper interfacing with RPMH. Signed-off-by: Sharat Masetty <smasetty@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
