    arm: use subsys_initcall in non-modular pl320 IPC code · 89f08f64
    Paul Gortmaker authored
    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 level 6-device to level 4-subsys (i.e. slightly
    earlier).  However no impact of that small difference is expected.
