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. ARM64 SoCs have additional peripherals at 0xff858000. On BCM6858 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 BCM6858 based on the vendor files 6858_map_part.h and 6858_intr.h from the "bcmopen-consumer" code drop. Curiously, on the BCM6858, the PL081 DMA block is separate from the two peripheral groups PERF and PERF1, so we put it in a separate node in the device tree since this is what the documentation says. This SoC has up to 256 possible GPIOs due to having 8 registers with 32 GPIOs in each available.
