arm64: dts: broadcom: Add firmware clocks and power nodes to Pi5 DT

Browse Source 
BCM2712 still uses the firmware clocks and power drivers, so add
them to the base device tree.

The brcm,bcm2836-l1-intc controller isn't used on this platform.
It is used on 32-bit kernels for the smp_boot_secondary hook, but
BCM2712 can't run a 32-bit kernel.
