[Intel-gfx] [PATCH 0/4] Drop support for pre-production DG2 hardware

[Matt Roper]

We generally only keep support for pre-production steppings and
workarounds around in the driver until the next major platform is
implemented.  Now that MTL is in good shape in i915 (and subsequent
platforms like LNL are being implemented solely on the Xe driver) it's
time to drop the DG2 pre-production hardware support.

DG2 production hardware always has display stepping C0 or later.  On the
GT side, production hardware starts with C0 (for DG2-G10), B1 (for
DG2-G11), and A1 (for DG2-G12).  This means we can drop quite a few
pre-production workarounds, and simplify the handling of several others.
