Kaanapali (SM8750) and Glymur use two display power domains.
CORE_GDSC powers the main display hardware while INT2_GDSC

I see that INT2_GDSC is defined since SC8280XP / SM8450. Does it need to
be enabled on all those platforms?
No, INT2_GDSC was introduced starting from Kaanapali for SSPP1
(VIG2/VIG3/DMA5). Prior to that, it was not actually used and
essentially served as a placeholder.
Sorry for the confusion. Glymur does not require INT2_GDSC to be enabled
either. I previously assumed it behaved the same way as Kaanapali, but
that assumption was incorrect.
Allow the MDSS bindings to describe both power domains and
their corresponding power-domain-names values.
