Add a second mapcache for grant mappings. The mapcache for
grants needs to work with XC_PAGE_SIZE granularity since
we can't map larger ranges than what has been granted to us.
Like with foreign mappings (xen_memory), machines using grants
are expected to initialize the
As of version DDI0487K.a of the Arm ARM, some architectural features
which previously didn't have official names have been named. Add
these to the list of features which QEMU's TCG emulation supports.
Mostly these are features which we thought of as part of baseline 8.0
support. For SVE and SVE2,

The current mapcache assumes that all memory is mapped
in a single RAM MR (the first one with offset 0). Remove
this assumption and propagate the offset to the mapcache
so it can do reverse mappings (from hostptr -> ram_addr).
This is in preparation for adding grant map

Newer versions of the Arm ARM (e.g. rev K.a) now define fields for

don't currently set the register value to non-zero.

Exposing SYSCFG inputs to the SoC is practical in order to wire the SoC

to be connected to both SYSCFG inputs and DM163 inputs).

Currently the sbsa_gdwt watchdog device hardcodes its frequency at

from the system counter, which also drives the CPU generic timers.
Newer CPU types (in particular from Armv8.6) should have a CPU
generic timer frequency of 1GHz, so
