The BCM958712DxXMC board is a smaller form factor typically used as
controller boards for switches. This smaller board has less devices
pinned out, so only a few need be populated in the device tree.

Nitro firmware is loaded into memory by the bootloader at a specific
location. Set this memory range aside to prevent the kernel from using
it.
