Subject: [RFC PATCH v9 4/7] arm64: dts: rockchip: Move PCIe WAKE# irq to pcie driver for Gru

Currently we are handling PCIe WAKE# irq in mrvl wifi driver.

Move it to rockchip pcie driver since we are going to handle it in the
pci core.

Also avoid this irq been considered as the PCI interrupt pin in the
of_irq_parse_pci().
