Mykola Kvach f8523357f0 docs/arm: Document GICv3 vCPU limit for host-layout domains ...

The number of vCPUs requested for a boot-time Arm domain is not bounded
solely by Xen's generic domain limits. For GICv3 domains using the host
memory layout, Xen can only create vCPUs whose virtual redistributor
frame is covered by redistributor MMIO regions exposed for that layout.

This can affect the hardware domain and direct-mapped domains. Document
the GICv3-specific limit in the `cpus` property description in the Arm
device-tree booting guide. Also add a generic domain-limit caveat to the
`dom0_max_vcpus` command-line documentation.
