Subject: drm/i915/ats-m: add ATS-M platform info
Git-commit: 412c942bdfae114bd3e1570936cef59d5aeb4f54
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
ATS-M is a server platform based on Xe_HPG and Xe_HPM, but without
display support. From a driver point of view, it's easiest to just
handle it as DG2 (including identifying as PLATFORM_DG2), but with the
display disabled in the device info.
