Also, I think we can provide a better commit message. I'll type something
in the morning when I can actually look stuff up and provide correct
references.

Note: This doesn't actually fix 110998. I can still get a hard-hang with a
slightly different version of the reproducer example. However, it does fix
the original and I suspect it will fix the UE4 editor hang in 110228

This is consistent with what the Windows driver does and what I've heard
from HW people.

This bit was fliped on for "syncing dependencies between camera and
graphics". BSpec has no recollection why, and it is causing
unrecoverable GPU hangs with Vulkan compute workloads.
From BSpec, setting bit5 to 0 enables relaxed padding requiremets for
buffers, 1D and 2D non-array, non-MSAA, non-mip-mapped linear surfaces;
and *must* be set to 0h on skl+ to ensure "Out of Bounds" case is
suppressed.
