The arm64 EFI boot support added a new 'dtb' value to the configuration file.
Update the documentation to describe this and how the coniguration file is not
used when GRUB loads the modules. Updates 'ucode' description to indicate that
it is x86 only.

Namely when making use the CONFIG_XEN_COMPAT_* options in the legacy
Linux kernels, newer kernels may not be compatible with older
hypervisors, so trying to boot such a combination makes little sense.
Booting older kernels on newer hypervisors, however, has to always
work.
With the way xen.efi looks for its configuration file, allowing
individual configuration files to refer only to compatible kernels,
and referring from an older- to a newer-hypervisor one (the kernels
of which will, as said, necessarily be compatible with the older
hypervisor) allows to greatly reduce redundancy at least in
development environments where one frequently wants multiple
hypervisors and kernles to be installed in parallel.

After commit 25594:ad08cd8e7097, EFI Xen binaries were installed to
/efi instead of /usr/lib64/efi. This patch restores the previous
behaviour established in commit 23645:638f31a30b6c.
