[PATCH 3/3] ARM: pxa: add module.h for spitz symbol_get/symbol_put usage

[Paul Gortmaker]

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.

mach-pxa/spitz.c: In function 'spitz_bl_kick_battery':
mach-pxa/spitz.c:524:2: error: implicit declaration of function 'symbol_get' [-Werror=implicit-function-declaration]
mach-pxa/spitz.c:524:12: warning: assignment makes pointer from integer without a cast [enabled by default]
mach-pxa/spitz.c:527:3: error: implicit declaration of function 'symbol_put' [-Werror=implicit-function-declaration]

It turns out this file uses symbol_get/symbol_put which live 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.

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.
