We already do this for the overlay fragment the driver injects and the

The background is that newer Linux kernel dislike IRQ_TYPE_NONE and
express that via WARN_ON during boot.

Log Message:
-----------
core: Fix paging_create when mapping single hugepages
When mapping hugepages, we try to clean up previous mappings of smaller
granularity for the target region first. Unfortunately, that could
destroy table entries in higher levels when the specific tree became
empty. This was easily reproducible by trying to map a single 2M region
at an address where there are no other mappings around.
The fix is to start the unmap with a subtree, rather than the full
paging tree. This way we will only clear entries at levels below the one
we are about to fill with a hugepage.
As it seems, the unmapping path is currently not used for practical
setups. The releasing impact could only by tested by artificially
defining two memory regions where the first one builds up a mapping with
3 levels and the second one overwrites this with only one level and a
hugepage. This case seems unlikely to occur with normal Jailhouse
reconfigurations. So we may consider dropping the cleanup path in the
future. It's fixed and kept for now to avoid surprises if the assumption
above no longer holds.

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.
This MMU driver will ID-map the following regions:
- 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)
