Tegra: organize memory/mmio apertures to decrease memmap latency
This patch organizes the memory and mmio maps linearly, to make the
mmap_add_region process faster. The microsecond timer has been moved
to individual platforms instead of making it a common step, as it
further speeds up the memory map creation process.
