ARM: dts: bcm63138: Add BCMBCA peripherals

All the BCMBCA SoCs share a set of peripherals at 0xff800000,
albeit at slightly varying memory locations on the bus and
with varying IRQ assignments.

Extend the peripheral interrupt window to 0x10000 as it need
to fit the DMA block.

Add the GPIO, RNG and LED and DMA blocks for the
BCM63138 based on the vendor files 63138_map_part.h and
63138_intr.h from the "bcmopen-consumer" code drop.

This SoC has up to 160 possible GPIOs due to having 5
registers with 32 GPIOs in each available.
