gpio: loongson1: fix implicit assumption module.h is present

The Kconfig for this file is:

drivers/gpio/Kconfig:config GPIO_LOONGSON1
drivers/gpio/Kconfig:   tristate "Loongson1 GPIO support"

...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.
