Revert "drm/i915: Extract intel_edp_fixup_vbt_bpp()"
This reverts commit a0f7cdd69ca3ba2c563d3d47f5c8f187feb36a75 which is
commit 822e5ae701af2964c5808b6ade1d6f3b1eaec967 upstream.
This is part of a series of i915 patches that were backported to 5.19.12
but found to be incomplete and caused problems on many systems so they
are being reverted.
