[PATCH 03/22] xen/arm: Remove __init from prototype

[Julien Grall <julien.grall@arm.com>]

In Xen, it is common to add __init to the declaration and not the
prototype. Remove the few __init on some prototypes which allows to
avoid the inclusion of init.h in headers.

With these changes, init.h is now required to be included on some c
files. Also, add __init where it was missing in declaration.
