Jetson TX2: fix root cell config for GPU acceleration
This patch fixes the root cell config for the Jetson TX2 platform to
avoid a deadlock occurring when using accelerated graphics. It maps the
VIC memory regions and increment the number of handled IRQs.

core: Fold map_root_memory_regions into init_late
It is safe to make this the very last step of init_late before
config_commit on all archs: it is only config_commit that depends on it,
and the region setup depends on the IOMMU being ready. And then we can
also fold this function into init_late directly.

Log Message:
-----------
core: Introduce unit infrastructure
This introduces the concept of functional units which can register
themselves with the core.
Each unit will then receive a number of callbacks on events of common
interest: hypervisor init and shutdown, cell creation and destruction,
and counting of MMIO regions per cell. All callbacks are mandatory, so
unused ones need to be stubbed. For the more common cases of missing
shutdown or mmio_count_regions callbacks, macros are provided. The init
callbacks are run in linking order, cleanup callbacks in the reverse
order.
Registration is performed by adding a unit structure to the units
section. From there, for_each_unit* iterators can pick them up in
linking order (or reversed).
The goal of this abstraction is to remove explicit hooks for the
mentioned events for each unit. It also allows to add a unit by simply
linking it against the hypervisor. This is specifically useful for
existing target-specific variations (e.g. CAT for Intel or VExpress
extensions) or upcoming optional features.
The reason to call this "unit", instead of "module", is to avoid
confusion with abstractions in Linux or other projects that have broader
semantics. E.g., a unit is not intended to become a runtime loadable
entity.

x86: Convert cat to a unit
This registers cat as a unit with the Intel-variant of the hypervisor.
For AMD, we just leave the non-unit'fied cat_update handler as weak stub
behind. cat_update is too special to model it as unit callback.

core: Rename arch_shutdown to arch_prepare_shutdown
On x86, arch_shutdown now only contains preparation steps that all have
to be called prior to issuing the shutdown to units. Rename the function
and also the iommu service it calls on x86 to reflect that. ARM and
ARM64 do not use it, thus is unaffected by this.
No functional changes.

This registers the amd_iommu or vtd a unit with the core, depending on
the hypervisor CPU-vendor variant. We do not use a shutdown hook but
rather continue to rely on the explicitly called iommu_prepare_shutdown
hook because the iommu need to close prior to other units.
