drm/i915/dg1: Update DMC_DEBUG3 register
Current DMC_DEBUG3(_MMIO(0x101090)) address is for TGL,
it is wrong for DG1. Just like commit
5bcc95ca382e
("drm/i915/dg1: Update DMC_DEBUG register"), correct
this issue for DG1 platform to avoid wrong register
being read.
BSpec: 49788
v2: fix "not wrong" typo. (Jani)
