drm/imagination: Implement free list and HWRT create and destroy ioctls
Implement ioctls to create and destroy free lists and HWRT datasets. Free
lists are used for GPU-side memory allocation during geometry processing.
HWRT datasets are the FW-side structures representing render targets.
Changes since v8:
- Corrected license identifiers
Changes since v6:
- Fix out-of-bounds shift in get_cr_multisamplectl_val()
Changes since v4:
- Remove use of drm_gem_shmem_get_pages()
Changes since v3:
- Support free list grow requests from FW
- Use drm_dev_{enter,exit}
