Subject: [PATCH 1/3] ARM: mach-omap2: remove bogus "or_module" from rx51-peripherals

During unrelated work, attempting to remove an include of the
linux/module.h in favour of "struct module;" in order to reduce
header entanglement, we found doing so caused a build failure in
this file.

It turns out this file uses __init_or_module which lives in the
module.h header, but it wasn't including module.h -- which was
being masked by the module.h in include/linux/gpio/driver.h - the
one we want to remove/replace.

However, if we dig into Makefile / Kconfig we find:

mach-omap2/board-rx51-peripherals.o ---->
   mach-omap2/Makefile:obj-$(CONFIG_MACH_NOKIA_RX51) += board-rx51-peripherals.o

arch/arm/mach-omap2/Kconfig:config MACH_NOKIA_RX51
arch/arm/mach-omap2/Kconfig:    bool "Nokia N900 (RX-51) phone"

...and hence the __init_or_module is pointless, as it will always
evaluate to plain __init.

With ARM and GPIO being different subsystems, we'll need to get
this in ARM 1st, and then wait a release before changing the GPIO
header, otherwise we'll risk triggering build failures.
