arm: dts: mt7623: add PCIe related nodes
This patch adds some device nodes for the PCIe function block and updates
related pinmux.
Moreover, we add interrupt-map properties in both parent and children as
the chip only has one IRQ per slot that is connected to all INTx and get
propagated through the bridges and it also represents the root ports own
interrupts.
