drm/xe: Add infrastructure for Device OOB workarounds

Browse source

Some workarounds need to be able to be applied ahead of any GT
initialization for example 15015404425. This patch creates XE_DEVICE_WA
macro, in the same vein as XE_WA. This macro can be used ahead of GT
initialization, and can be tracked in sysfs. This should alleviate some
of the complexities that exist in i915.

v2: name change SoC to Device, address style issues
v5: split into separate patch from RTP changes, put oob within a struct,
move the initiation of oob workarounds into xe_device_probe_early(),
clean up the comments around XE_WA.
