arm-common: Remove redundant statement for SGI routing mode 2
In case of mode 2, the targets field won't be evaluated. So we can save
one statement, initialized targets to 0 unconditionally, and instead
invest in explaining when we need to tune it further.

arm-common: Clearify the role of gicv2_target_cpu_map in GICv3 mode
What we do on GICD_SGIR in GICv3 mode with affinity routing on is not
obvious. Leave a comment.

arm: Declare each redistributor region to be last
As long as we are virtualizing MPIDR and, thus, also the region layout,
we can easily mark the end. However, when removing this virtualization
and starting to hand out the regions as-is, it will become complex to
identify contiguous ones.
To make this simple (for the hypervisor), just declare each of them to
be last. That means we will have to construct device trees for non-root
cells that declare multiple redistributor regions, even if they are
physically contiguous.

arm: Switch redistributor handling completely to MMIO dispatcher
We can avoid the extra loop in gic_handle_redist_access just to map the
virtual GICR address to its corresponding CPU. We just need to register
one redist region per cell CPU.

arm: Detect unsupported Aff0 values in MPIDR
Just to be safe: ICC_SGI1R_EL1 allows us to address at most 16 cores in
the most significant affinity level. Encode this restriction in the init
code because we will rely on it during runtime.

arm, arm64: Move gicr per-cpu parameter into struct
This prepares for adding another GICv3 parameter later on.
ARM64 is not using the field yet, but it already carries it. So update
this side as well.

arm, arm64: Track physical address of redistributors for each CPU
We will need this once we start to identity-map the redistributors. And
while we could currently still calculate the addresses, better prepare
for multiple redist regions and store the address along the mapping.
Again, the update on ARM64 is just to prepare for eventually sharing the
GICv3.

arm: Remove MPIDR virtualization
Do not modify the MPIDR value that the cells see. VMPIDR is initialized
to the physical MPIDR on reset, and we can safely keep this, even while
the GICv2 IDs are still virtualized because they are unrelated.
We just need to adjust the GICv3 case because there we are in affinity
routing mode, and the MPIDR does play a role when dispatching SGIs.
GICR_TYPER can now be kept almost unmodified. Moreover, the
redistributors needs to be identity-mapped into the guests.
This also aligns arm with arm64 and will help introducing GICv3 to the
latter.
