[Mesa-dev] [PATCH 2/2] anv/device: Fix max buffer range limits

[Nanley Chery]

Set limits that are consistent with ISL's assertions in
isl_genX(buffer_fill_state_s)() and Anvil's format-DescriptorType
mapping in anv_isl_format_for_descriptor_type().

Fixes the following new crucible tests:
* stress.limits.buffer-update.range.uniform
* stress.limits.buffer-update.range.storage

These tests are in this patch: https://patchwork.freedesktop.org/patch/98726/
