armv7: use start and size parameters in mmu_setup() 

mmu_setup() was originally written in U-Boot to utilize board-specific
global data. Since we're trying to avoid that, we added start and size
parameters so that board-specific info can be passed in via mainboard
code. Let's start using it that way.
