This patch gets rid of the MMIO_P2V and __MMIO_P2V macros,
defining constant virtual base for motherboard and tile
peripherals instead.
Additionally, in preparation for the new motherboard memory
map, the motherboard peripherals are using base pointers
calculated in runtime, instead of compile-time calculated
values.

The current Versatile Express BSP defines the MACHINE_START macro
in the core tile code.
This patch moves this into the generic board code and introduces a
method for determining the current tile at runtime, allowing the
Kernel to have support for multiple tiles compiled in. Tile-specific
functions are executed via a descriptor struct containing the correct
implementations for the current tile.
