The Rockchip DSI driver has had a number of bugs over time and has
usually only worked by chance. A number of users have noticed that
things regressed with commit 43c2de1002d2 ("drm/rockchip: dsi: move all
lane config except LCDC mux to bind()"), although it was fixing several
real issues of its own that had been present forever in the upstream
driver (but notably, not in the downstream/BSP driver).
Patch 1 is the most important fix here. See its description for more
info.
While I'm at it, fix a few error handling and cleanup issues too.
Changes in v2:
- Clean up pm-runtime state in error cases.
- Correct git hash for Fixes.

drm/rockchip: dsi: Hold pm-runtime across bind/unbind
drm/rockchip: dsi: Fix unbalanced clock on probe error
drm/rockchip: dsi: Disable PLL clock on bind error
