[Intel-gfx] [PATCH 10/10] drm/i915/tgl: Added new DC5/DC6 counter.

[Anshuman Gupta]

TGL onwards we have new DC5 and DC6 counter
DMC_DEBUG1 and DMC_DEBUG2 these counter will retain
there values upon DMC reset.
Currently using IS_GEN() macro instead of IS_TIGERLAKE()
to avoid compilation error and flot the pacthes.
Will be using IS_TIGERLAKE() once TGL platform
enabling pacthes merged to drm-tip.
