We'd like to add safeguards against accidental use of MOCS 0 (uncached),
which can have large performance implications. One case where we use
MOCS of 0 is SURFTYPE_NULL surfaces, where MOCS really shouldn't matter,

That said, it should be harmless to set MOCS for these null surfaces;
we can just assume a generic MOCS for internal buffers.

We're going to start asserting for valid halign/valign values during
surface state emission. Pre-SKL, isl_surf_get_uncompressed_surf creates
uncompressed surfaces with invalid halign/valign values - 1x1. Fix this
by replacing the call to isl_surf_get_image_surf with isl_surf_init,
passing in the uncompressed format up-front.
As we're no longer using isl_surf_get_image_surf, we also need to get
the x and y offset of the image ourselves. Instead of getting a
sample-based offset, then converting to elements later on, we use
isl_surf_get_image_offset_B_tile_el to get the offset in elements
up-front.
With the above two changes, the generic code after the else-block is no
longer needed for the single-layer-view code path. We move it and
specialize it to the if-block (which is executed SKL+ and handles
multi-layer views).

Implement the workarounds in anv and iris instead.
Before this commit, ISL unconditionally modified workaround registers
while filling out depth stencil state. To account for this, drivers
unconditionally stalled prior to emitting depth stencil packets. This
hurt performance.
By having the drivers perform the workarounds, they can choose when to
modify the relevant registers. The drivers now avoid emitting the
workaround for NULL depth buffers. This reduces stalls and leads to
better performance.

This gets rid of the awkward interface for isl_surf_get_ccs_surf where

Instead, we now pass it three well-labled surfaces: surf,
hiz_or_mcs_surf, and ccs_surf which have obvious meanings. This does
mean that iris has to carry a bit of logic and we have to flip
parameters around in all the callers. But the resulting interface is

probably should. In particular, we were really only checking HiZ
