CORE_GDSC powers the main display hardware while INT2_GDSC powers a subset of SSPP blocks (VIG2/VIG3/DMA5/DMA6). Add DISP_CC_MDSS_CORE_INT2_GDSC alongside the existing CORE_GDSC reference in the MDSS node on both platforms and provide matching power-domain-names entries for the display power domains.
