Detect and use passed dtb address using the UHI interface. This allows for
booting with a vmlinux.bin appended dtb instead of using a built-in one.

Add a DTS file and Kconfig entry for the BCM97435SVMB evaluation board
using bcm7435.dtsi as an example.
The current code needs some tweaking to allow us to use the
dual-threaded dual BMIPS5200 CPUs, so for now we limit ourselves to
allowing just a single CPU to be booted.

Since we are always sourcing arch/mips/bmips/Kconfig and there is no
dependency on BMIPS_GENERIC, we will offer building BMIPS-related DTBs
while this is not relevant for the other MIPS platforms.

Most of the supported chips use legacy (non-DT) bootloaders, so they will
need to select an appropriate builtin DTB at compile time until the
bootloader is updated. Provide suitable DTS files, and a means to compile
one of them into the kernel image.

BCM3384/BCM63xx can use the common drivers/irqchip/irq-bcm7120-l2.c for
this purpose; BCM7xxx will use drivers/irqchip/irq-bcm7038-l1.c. We no
longer need this code under arch/mips.

A couple of chips require special handling in order to make SMP secondary
boot and/or exception vectors work correctly. Take care of these in
setup.c.

There is no "bcm3384" bus so let's just remove it to avoid confusion.

This is a more standardized way of handling DMA remapping, and it is
suitable for the memory map found on BCM3384.

This platform is configured primarily through device tree, and we can
reuse the same code to support a bunch of other chips. Change the name
to reflect this.
