[PATCH 05/97] drm/i915/guc: use probe_error log for CT enablement failure

[Matthew Brost]

From: Daniele Ceraolo Spurio <daniele.ceraolospurio at intel.com>

We have a couple of failure injection points in the CT enablement path,
so we need to use i915_probe_error() to select the appropriate log level.
A new macro (CT_PROBE_ERROR) has been added to the set of CT logging
macros to be used in this scenario and upcoming ones.

While adding the new macros, fix the underlying logging mechanics used
by the existing ones (DRM_DEV_* -> drm_*) and move the inlines to
before they're used inside the macros.
