As described in the comment on intel_detect_preproduction_hw(),

   Our policy for removing pre-production workarounds is to keep the
   current gen workarounds as a guide to the bring-up of the next gen
   (workarounds have a habit of persisting!). Anything older than that
   should be removed along with the complications they introduce.

TGL and DG1 are well past the point where we should move forward with
removing the hardware workarounds specific to internal/pre-production
hardware.

JSL/EHL appear to have productized A0 hardware, so all workarounds for
those platforms will stay in the driver forever.  We can probably remove
some pre-production workarounds for RKL and ADL at this point as well,
but the bspec doesn't have details about which steppings were only used
in pre-production, so we'll need to track down that information later.
