[PATCH 10/73] powerpc: use device_initcall for registering rtc devices

From: Paul Gortmaker
Date: Tue Jan 21 2014 - 16:29:57 EST

Currently these two RTC devices are in core platform code
where it is not possible for them to be modular. It will
never 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.

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 device_initcall
directly in this change means that the runtime impact is
zero -- they will remain at level 6 in initcall ordering.
