gpio: altera: fix implicit assumption module.h is present
The Kconfig for this file is:
drivers/gpio/Kconfig:config GPIO_ALTERA
drivers/gpio/Kconfig: tristate "Altera GPIO"
...but however it does not include module.h -- it in turn gets it from
another header (gpio/driver.h) and we'd like to replace that with a
forward delcaration of "struct module;" but if we do, this file will
fail to compile.
So we fix this first to avoid putting build failures into the bisect
commit history.
