drm/i915/adlp+: Allow DC states along with PW2 only for PWB functionality
A recent bspec update added a restriction on when DC states can be enabled:
[Before enabling DC states:]
"""
PG2 can be kept enabled only because PGB requires PG2.
Do not use PG2 functions, such as type-C DDIs.
DMC will dynamically control PG1, PGA, PG2, PGB.
"""
Accordingly prevent DC states if PW2 (aka PG2) is enabled for any other
functionality.
Bpsec: 49193
Fixes: 88c487938414 ("drm/i915: Use separate "DC off" power well for ADL-P and DG2")
