[PATCH v2 13/17] drm/i915: cleanup: drm_modeset_lock_all() --> DRM_MODESET_LOCK_ALL_BEGIN() part 2

amd-gfx, dri-devel, intel-gfx, linux-arm-msm, linux-renesas-soc, linux-tegra, lkml, nouveau
Subsystem:
drm drivers, intel drm display for xe and i915 drivers, intel drm i915 driver (meteor lake, dg2 and older excluding poulsbo, moorestown and derivative), the rest · Maintainers:
David Airlie, Simona Vetter, Jani Nikula, Rodrigo Vivi, Joonas Lahtinen, Tvrtko Ursulin, Linus Torvalds
As requested in Documentation/gpu/todo.rst, replace driver calls to drm_modeset_lock_all() with DRM_MODESET_LOCK_ALL_BEGIN() and DRM_MODESET_LOCK_ALL_END() While the previous commit was a simple "search and replace", this time I had to do a bit of refactoring as only one call to DRM_MODESET_LOCK_ALL_BEGIN() is allowed inside one same function.
