drm/imagination: Implement firmware infrastructure and META FW support
The infrastructure includes parsing of the firmware image, initialising
FW-side structures, handling the kernel and firmware command
ringbuffers and starting & stopping the firmware processor.
This patch also adds the necessary support code for the META firmware
processor.
Changes since v8:
- Fix documentation for pvr_fwccb_process()
- Corrected license identifiers
Changes since v6:
- Add a minimum retry count to pvr_kccb_reserve_slot_sync()
Changes since v5:
- Add workaround for BRN 71242
- Attempt to recover GPU on MMU flush command failure
Changes since v4:
- Remove use of drm_gem_shmem_get_pages()
- Remove interrupt resource name
Changes since v3:
- Hard reset FW processor on watchdog timeout
- Switch to threaded IRQ
- Rework FW object creation/initialisation to aid hard reset
- Added MODULE_FIRMWARE()
- Use drm_dev_{enter,exit}
