The UARTs are outputting garbage on the console. This is due to a speed
issue. We can simply use the clock speed (which is now defined in the
DTSI file) and everything works fine.

Memory starts at 0x80000000, not 0. 0 "works" due to mirrior of the
first 128M of RAM to that address. Anything greater than 128M will
quickly find nothing there. Correcting the starting address has
everything working again.
