[PATCH 12/12] ARM64: dts: bcm63158: Add BCMBCA peripherals

with varying IRQ assignments. On BCM63158 the PERF window was
too big so adjust it down to its real size (0x3000).

Add the watchdog, GPIO blocks, RNG, LED, second UART and DMA
blocks for the BCM63158 based on the vendor files 63158_map_part.h
and 63158_intr.h from the "bcmopen-consumer" code drop.

The DTSI file has clearly been authored for the B0 revision of
the SoC: there is an earlier A0 version, but this has
the UARTs in the legacy PERF memory space, while the B0
has opened a new peripheral window at 0xff812000 for the
three UARTs. It also has a designated AHB peripheral area
at 0xff810000 where the DMA resides, so we create new windows
for these two peripheral group reflecting the internal
structure of the B0 SoC.

This SoC has up to 256 possible GPIOs due to having 8
registers with 32 GPIOs in each available.
