Jitao Shi b54bc0013d drm/mediatek: Separate poweron/poweroff from enable/disable and define new funcs
[ Upstream commit cde7e2e35c ]

In order to match the changes of "Use the drm_panel_bridge API",
the poweron/poweroff of dsi is extracted from enable/disable and
defined as new funcs (atomic_pre_enable/atomic_post_disable).

Since dsi_poweron is moved from dsi_enable to pre_enable function, in
order to avoid poweron failure, the operation of dsi register fails to
cause bus hang. Therefore, the protection mechanism is added to the
dsi_enable function.

Fixes: 2dd8075d21 ("drm/mediatek: mtk_dsi: Use the drm_panel_bridge API")
