Unlike Gen11, Gen12 hardware supports up to three pixel pipes per
slice.
Unfortunately the kernel interface is somewhat inconsistent between
Gen11 and Gen12: I915_PARAM_SUBSLICE_MASK returns a mask of enabled
*dual* subslices since TGL, so there is half the number of bits per
pixel pipe in the mask. This is worked around here so we're able to
calculate the correct size of each pixel pipe, but the result is
returned in dual subslice units, inheriting the inconsistency from the
kernel -- Reason is that as of now all our Gen12 subslice counts
returned by gen_device_info.c are really dual subslice counts, and the
num_eu_per_subslice counts are also scaled accordingly, so it seems
like it would only make the matter worse if I fixed the units of this
field only without also fixing the rest.

Kernel support for DG1 has not yet been merged upstream; per our
long-standing DRM subsystem policy, we should not enable the platform
in userspace until the kernel patches are merged and functional.
We will re-enable this in the future. In the meantime, we retain all
of the infrastructure and code for the platform so that we can continue
developing DG1 support in upstream.

On all Gen7+ platforms except DG1, the URB is a subsection of the
configurable L3 cache, and so the size can vary. The size listed
in the documentation on those platforms is an "example size", picked
by calculating it based on an arbitrarily chosen L3 config.
Hardcoding a value for those platforms provides no value and only
confuses people trying to fill out these tables when doing hardware
enabling. anv and iris never use this field. i965 uses it to
initialize brw->urb.size, but then updates that in update_urb_size()
to be the correct value, so the initial value doesn't matter.
Delete the values for Gen7+ and update the comment accordingly.

Found by inspection, I'm not aware of any bugs caused by this typo.
According to Lionel, it seems we only use this to generate masks
of available EUs for perfromance queries, and it's only used when we
can't query the fused parts of the GPU through DRM_IOCTL_I915_QUERY.
So this patch should help for the corner case where the Kernel is too
old to support the query ioctl.
