The hardware writes one CRC per (effective) tile, the tile size of the CRC
buffer is the same as the configured effective tile size. However, all our CRC
infrastructure assumes 16x16 tiles. In case CRC is used with smaller tiles,
buffer overflows and incorrect rendering are all possible. Don't use CRC at
smaller tile sizes. Note disabling CRC correctly invalidates any bound CRC
buffers.

The struct is returned from a function, so in debug builds the address
may change after returning, and pointers to patched_s will be broken.
Pass the pointer to the patched stencil view as a parameter to
pan_preload_get_views to avoid this.

In 3559efb9bf ("panfrost: Allow passing an explicit UBO index for the
sysval UBO"), an explicit UBO index was added and it was implicitly
assumed that it would be > num_ubos. This was convenient because it
meant 0, the default for designated initializers, implicitly meant
compiler-assigned. However, we're about to move the sysval UBO to 0
which breaks this assumption. Also, we don't want the back-end
compiler to even look at num_ubos since it's meaningless in Vulkan.

We always blit from a particular level, so it's a waste to compute the LOD.
This corresponds to a simple texture instruction with implement 0 LOD, which is
the optimal texturing path on Bifrost -- it maps to TEXS_2D but does not require
helper invocations.
Functional change on Bifrost: Blit shaders no longer set .computed_lod or
shader_contains_barrier.

Fixes several problems in the pan_blit() logic:
1. We actually need the reciprocal of the depth scaling in z_scale (maybe
we should rename this field z_scale_rcp to make it clear)
2. When Z end < Z start we should remove one to the cur_layer/layer_offset
instead of doing it on the last_layer field, otherwise there's an
off-by-one error
3. The Z src offset should be adjusted to account for scaling. If we don't
do that we won't sample from the right layer when upscaling.

The Gallium and Vulkan drivers will soon use different memory pool
implementation, but some pieces in libpanfrost depend on pan_pool. Let's
split the implementation so we have common bits still available while
letting the drivers implement what really matters: the allocation logic.
All the generic pieces are prefixed pan_pool, and what will become the
gallium implementation is prefixed panfrost_pool. We'll then duplicate
the panfrost_pool bits in panvk and prefix it with panvk_pool, and
implementations will start diverging from there.

CRC is intended for final render targets and especially for UI, not the
kind of things you'd mipmap. Meanwhile CRC only works for a single
level, meaning at any given point, half the CRC buffer would be wasted
for a full miptree.
"Arm Mali Best Practices Guide" tells developers that the DDK only
enables CRC for non-mipmapped resources (at least the Vulkan DDK), so
let's do the same, save some memory, and simplify our code.
