drm/imagination: Add firmware trace to debugfs
Firmware trace is exposed at /sys/debug/dri/<dev_nr>/pvr_fw/trace_0.
Trace is enabled via the group mask at
/sys/debug/dri/<dev_nr>/pvr_params/fw_trace_mask.
Changes since v8:
- Corrected license identifiers
Changes since v3:
- Use drm_dev_{enter,exit}
