[PATCH 1/3] dt-bindings: display: msm: Allow two MDSS power domains

[Yongxing Mou]

Kaanapali (SM8750) and Glymur use two display power domains.
CORE_GDSC powers the main display hardware while INT2_GDSC
powers a subset of SSPP blocks.

Allow the MDSS bindings to describe both power domains and
their corresponding power-domain-names values.
