[PATCH v11 6/9] drm/msm/dpu: always clear every individual pending flush mask

[Kuogee Hsieh]

There are two tiers of pending flush control, main controller and
individual hardware block. Currently only the main controller of
flush mask is reset to 0 but leave out some individual pending flush
mask of particular hardware block keep previous value at
clear_pending_flush(). Reset all individual hardware blocks flush
mask to 0 to avoid individual hardware block be triggered accidentally.
