Snapshot of SDE driver. This includes DRM SDE, DP, and DSI drivers,
v4l2 rotator driver, and clk driver for display plls. Upstream changes
to drm/msm have been merged but require further fixes and validation
before enabling this driver. Snapshot was taken from msm-4.9 as of:
commit f54b6540b397 ("wil6210: add proper locking in cfg suspend")
