This was implemented in the driver but not actually defined and referenced in dts. This makes it always on. From reference manual in section "10.4.1.4.1 Power Distribution": "Display domain - The DISPLAY domain contains GIS, CSI, PXP, LCDIF, PCIe, DCIC, and LDB. It is supplied by internal regulator." The current pd_pcie is actually only for PCIE_PHY, the PCIE ip block is actually inside the DISPLAY domain. Handle this by adding the pcie node in both power domains.
