drm/i915/dmc_wl: Show description string for enable_dmc_wl

Browse Source 
We already provide the value resulting from sanitization of
enable_dmc_wl in dmesg, however the reader will need to either have the
meanings memorized or look them up in the parameter's documentation.
Let's make things easier by providing a short human-readable name for
the parameter in dmesg.
