This patch introduces initial workarounds for mtl platform

v2: switch IS_MTL_DISPLAY_STEP to use IS_METEORLAKE from testing display
ver. (Tvrtko)

v3: clerical issues, extend 16015201720 to mtl. (MattR)

v4: make sure 16015201720 includes display 13. (MattR)

Bspec: 66624

I'm planning to send a couple patches to clean these up across the
driver soon.  Today they're handled in an inconsistent manner throughout
the driver, some of them haven't been updated when the corresponding
code conditions got updated, etc.  I'll want to audit all of the bounds
again too to make sure we haven't overlooked any adjustments to the
workaround database.

I probably won't get to this until after the new year, but it's on my
todo list.

Sounds good.

What is the clean up plan - remove them all or sync with reality?
