Implement support for fetching the hardware description table from the
GuC. The call is made twice - once without a destination buffer to
query the size and then a second time to fill in the buffer.
Note that the table is only available on ADL-P and later platforms.

The DRM_I915_QUERY_HWCONFIG_BLOB query item returns a blob of data
which it receives from the GuC software. This blob provides some
useful data about the hardware for drivers.
Although the blob is not fully documented at this time, the basic
format is an array of u32 values.
This is John/Rodrigo's 2 patches with some minor changes, and I added
2 patches.
"drm/i915/uapi: Add query for hwconfig blob" was changed:
* Rename DRM_I915_QUERY_HWCONFIG_TABLE to DRM_I915_QUERY_HWCONFIG_BLOB
as requested by Joonas.
* Reword commit message
* I added Acked-by to this

Ah, sorry thanks for pointing that out. We did discuss previously. I
will go ahead and change it.

The driver is set currently to fail modprobe when GuC is disabled
(enable_guc=0) after GuC has been loaded on a previous modprobe.
For GuC deprivilege, the BIOS is setting the locked bit, so the
driver always considers the GuC

The omap KMS driver will call drm_plane_create_color_properties() with
a default encoding and range values of BT601 and Full Range,
respectively.
Since the initial value wasn't carried over in the state, the driver had
to set it again in omap_plane_reset(). However, the helpers have been
