The secondary XHCI controller, using a PHY that is shared between it and the secondary PCI-Express controller, gets powered by the PCIE_MAC_P1 power domain. Add this power domain to the usb@11290000 node to fix probe. Fixes: 37f2582883be ("arm64: dts: Add mediatek SoC mt8195 and evaluation board") Reported-by: Nícolas F. R. A.
