Subject: [PATCH AUTOSEL 5.15 09/46] Revert "drm/amd/display: Limit max DSC target bpp for specific monitors"

From: Hamza Mahfooz <hamza.mahfooz@....com>

[ Upstream commit 6803dfd3a69ccb318772463a86e40929fd4fbac7 ]

This reverts commit 55eea8ef98641f6e1e1c202bd3a49a57c1dd4059.

This quirk is now handled in the DRM core, so we can drop all of
the internal code that was added to handle it.
