gpiolib: make gpio_device_get() and gpio_device_put() public
[ Upstream commit 36aa129f221c9070afd8dff03154ab49702a5b1b ]
In order to start migrating away from accessing struct gpio_chip by
users other than their owners, let's first make the reference management
functions for the opaque struct gpio_device public in the driver.h
header.
