[Intel-gfx] [PATCH] drm/i915/mtl: Drop Wa_14017240301

[Matt Roper]

Drop Wa_14017240301, which is only relevant to pre-production MTL
hardware.  Although we usually wait a little bit longer to start
dropping pre-production workarounds for a platform, it was suggested to
eliminate this one slightly earlier because it's a bit unusual/ugly:
this workaround is a display-specific workaround that requires matching
on the graphics/GT IP version instead of the display IP version.
