Thanks for review.

Sometime ago, I got the comiplation error on random config for one of 
architecture which was not having GPIO architecture. The compilation 
error was reported on tps62360-regulator.c which is also using similar 
i2c calls.

So to avoid similar issue, I make this depends on GPIOLIB.

However, I looked gpio.h and it has all required APIs as static inline 
if GPIOLIB is not there so atleast compilation issue will not be there.

Now going through code, I think if gpios are not there then also it 
should work.
Not tested this on my board as I can not boot without gpio.

I think we can drop this patch.

Thanks,
Laxman
