inmates: arm: move calculation of CONFIG_INMATE_BASE to inmate_common.h
We need to id-remap our own inmate. Therefore it needs to know its own
base address. Currently, the base address is determined by
CONFIG_INMATE_BASE in config.h.
So far, only linker scripts used this definition. Now we need it for
both: the linker script and in the code. Move it to inmate_common.h

inmates: arm-common: implement common map_range routine
map_range() id-maps pages. Pages may either be uncached (e.g., MMIO) or
cached (e.g., RAM).
On arm and arm64, we only use two level paging. On both architectures,
we will enter level one, IOW we skip level zero on arm64. The first
level page table (the page directory) is allocated statically, the
second level page tables (page middle directores, which have 512
entries) will dynamically be allocated as needed.
As we only use level one and two, the paging granularity well be 2MiB
(HUGE_PAGE_SIZE), same as for x86.

inmates: arm-common: add MMU support
Basically, the MMU on both ARM architectures work in the same way.
There are only slight differences in register naming and their content.
But the 'same' set of registers needs to be written. By abstracting
registers and their content to sysregs.h, we're now able to use the same
MMU driver code for both architectures.
Device drivers will ID-map the regions they are touching:
- Base address of the inmate, length 0x10000 (results in 2MiB)
- Communication Region, length 0x1000 (results in 2MiB)
- UART, if existent, length 0x1000 (results in 2MiB)
- GIC[CD|DR], length 0x1000 (results in 2MiB)
