asm-generic/gpio.h: add some forward decls of the device struct
After the recent commit a4177ee7f, attempting to include asm-generic/gpio.h in otherwise "slim" code results in ugly warnings like so: CC arch/blackfin/kernel/bfin_gpio.o In file included from arch/blackfin/include/asm/gpio.h:278, from arch/blackfin/kernel/bfin_gpio.c:15: include/asm-generic/gpio.h:193: warning: ‘struct device’ declared inside parameter list its scope is only this definition or declaration, which is probably not what you want So add simple C forward decls of the struct device to avoid these.
