[Intel-gfx] [PATCH v2 13/27] dyndbg: add __pr_debug_cls(class, fmt, ...)

[Jim Cromie]

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.  But test_dynamic_debug needs it in order to demonstrate all
the moving parts.

Note the __ prefix; its not intended for general use, and doesn't
include any builtin-constant checks that could pertain.  I'd prefer to
see a use-case where copying the drm.debug model isn't better.
