arm,arm64/xen: move Xen initialization earlier
Currently, Xen is initialized/discovered in an initcall. This doesn't
allow us to support earlyprintk or choosing the preferred console when
running on Xen.
The current function xen_guest_init is now split in 2 parts:
- xen_early_init: Check if there is a Xen node in the device tree
and setup domain type
- xen_guest_init: Retrieve the information from the device node and
initialize Xen (grant table, shared page...)
The former is called in setup_arch, while the latter is an initcall.
