Devices of bcm283x have different base address, depending if they are on
bcm2835 or bcm2836/7. Use BCM283x_BASE depending on the SoC you want to
build and only add the offset in the header files.

How hard would it be to make the base a global variable instead and just
set it early on board init based on the FDT or maybe even CPU core
revision registers?
That would allow us to support RPi3 & 4 with the same U-Boot binary.
