arm: Reorganise and document memory map
The hardcoded memory map we expose to a guest is currently described
using a series of partially interconnected preprocessor constants,
which is hard to read and follow.
In preparation for moving the UART and RTC to some different MMIO
region, document the current map with some ASCII art, and clean up the
definition of the sections.
This changes the only internally used value of ARM_MMIO_AREA, to better
align with its actual meaning and future extensions.
No functional change.
