[PATCH v2 0/6] drm/imagination: Add async VM_BIND with sparse mappings

[Gyeyoung Baek <gye976@gmail.com>]

Userspace MR:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/43794

This series is for Vulkan sparse binding.

- Patches 1-2 switch the GPUVM to immediate mode.
- Patch 3 moves the existing map and unmap paths onto a single bind
  entry point.
- Patch 4 adds the VM_BIND ioctl.
- Patch 5 adds asynchronous requests.
- Patch 6 adds sparse mappings.

Patches 1-2 were sent separately [1]. They conflict with drm-misc-next,
so they are rebased and included here.

Testing:
Tested on BeagleY-AI.
- The existing IGT pvr_vm_map passes without regressions.
- dEQP-VK.sparse_resources passes for the sparse features the Mesa MR
  above exposes.

Changes in v2:
- New patch 3, "Route map and unmap through pvr_vm_bind()".
- Split v1 3/4 into the ioctl (4) and the asynchronous mode (5).
- Bump the driver interface version to 1.2, as 1.1 is already taken by
  another patch.
- Link to v1: https://lore.kernel.org/r/20260817-pvr-vm-bind-v1-0-0a0f21be7d38@gmail.com
