[PATCH 2/2] gpio: do not call __gpio_xxx under !CONFIG_GPIOLIB

[Yuanhan Liu]

Those functions are availabe only when CONFIG_GPIOLIB is set. So, we
should not call them under !CONFIG_GPIOLIB block.

This would fix following build errros:
include/asm-generic/gpio.h: In function 'gpio_get_value_cansleep':
include/asm-generic/gpio.h:220:2: error: implicit declaration of function '__gpio_get_value'
include/asm-generic/gpio.h: In function 'gpio_set_value_cansleep':
nclude/asm-generic/gpio.h:226:2: error: implicit declaration of function '__gpio_set_value'
