Split the function of "enable_guc_submission" into two separate
options. The new one ("enable_guc_loading") controls only the
*fetching and loading* of the GuC firmware image. The existing
one is redefined to control only the *use* of the GuC for batch
submission once the firmware is loaded.
In addition, the degree of control has been refined from a simple
bool to an integer key, allowing several options:
-1 (default) whatever the platform default is
0 DISABLE don't load/use the GuC
1 BEST EFFORT try to load/use the GuC, fallback if not available
2 REQUIRE must load/use the GuC, else leave the GPU wedged
The new platform default (as coded here) will be to attempt to
load the GuC iff the device has a GuC that requires firmware,
but not yet to use it for submission. A later patch will change
to enable it if appropriate.
v4:
Changed some error-message levels, mostly ERROR->INFO, per
review comments by Tvrtko Ursulin.
v5:
Dropped one more error message, disabled GuC submission on
hypothetical firmware-free devices [Tvrtko Ursulin].
v6:
Logging tidy by Tvrtko Ursulin:
* Do not log falling back to execlists when wedging the GPU.
* Do not log fw load errors when load was disabled by user.
* Pass down some error code from fw load for log message to
make more sense.
