The drivers/mailbox/pl320-ipc.o is dependent on config PL320_MBOX
which is declared as a bool.  Hence the code is never going to be
modular.  So using module_init as an alias for __initcall can be
somewhat misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.  Also add an inclusion of init.h, as
that was previously implicit.

Note that direct use of __initcall is discouraged, vs. one of the
priority categorized subgroups.  As __initcall gets mapped onto
device_initcall, our use of subsys_initcall (which seems to make
sense for IPC code) will thus change this registration from a
level 6-device to a level 4-subsys (i.e. slightly earlier).
However no impact of that small difference is expected.
