drm/xe/uapi: Add IP version and stepping to GT list query
For modern platforms (MTL and later), both kernel and userspace drivers
are expected to apply GT programming and workarounds based on the IP
version and stepping self-reported by the GT hardware via the the GMD_ID
registers. Since userspace drivers can't access these registers
directly, pass along the version and stepping information via the GT
list query. Note that the new query fields will remain 0's when running
on pre-GMD_ID platforms. Userspace is expected to continue using PCI
devid / revid on those older platforms.
Although the hardware also has a GMD_ID register for display
version/stepping, that value is intentionally *not* included anywhere in
the Xe uapi. Display userspace should be using platform-agnostic APIs
and auto-detecting platform capabilities rather than matching specific
IP versions.
