For selftest purposes, add __pr_debug_cls(class, fmt, ...)
I didn't think we'd need to define this, since DRM effectively has it
already in drm_dbg, drm_devdbg. But test_dynamic_debug needs it in
order to demonstrate all the moving parts.
Note the __ prefix; its not intended for general use, at least until a
need emerges. ISTM the drm.debug model (macro wrappers inserting enum
const 1st arg) is the baseline approach.
NB: it does require a builtin-constant class, no __pr_debug_cls(i"",...)
