[Intel-gfx] [PATCH] drm/i915/display: replace boilerplate code with helper macros

[Hamza Mahfooz <someguy@effective-light.com>]

As per commit 22be87401289 ("drm: TODO: Add DRM_MODESET_LOCK_ALL*
conversion to todo.rst"),
drm_modeset_lock_all()/drm_modeset_unlock_all() and boilerplate code
surronding instances of drm_modeset_lock_all_ctx() with a local acquire
context should be replaced with the relevant helper macros.
