[Intel-gfx] [PATCH 13/28] drm/i915/tgl: Add new pll ids

From: Vandita Kulkarni <vandita.kulkarni at intel.com>

Add 2 new PLLs for additional TC ports. The names for the PLLs on TGL
changed, but most registers remained the same, like MGPLL5_ENABLE,
MGPLL6_ENABLE. So continue to use the name from ICL.
