drm/i915/guc: Combine enable_guc_loading|submission modparams
We currently have two module parameters that control GuC:
"enable_guc_loading" and "enable_guc_submission". Whenever
we need submission=1, we also need loading=1. We also need
loading=1 when we want to want to load and verify the HuC.
Lets combine above module parameters into one "enable_guc"
modparam. New supported bit values are:
0=disable GuC (no GuC submission, no HuC)
1=enable GuC submission
2=enable HuC load
Special value "-1" can be used to let driver decide what
option should be enabled for given platform based on
hardware/firmware availability or preference.
Explicit enabling any of the GuC features makes GuC load
a required step, fallback to non-GuC mode will not be
supported.
v2: Don't use -EIO
v3: define modparam bits (Chris)
v4: rely on implicit cast (Chris)
