gpiolib: add drivers/gpio directory
Add an empty drivers/gpio directory for gpiolib infrastructure and GPIO
expanders. It will be populated by later patches.
This won't be the only place to hold such gpio_chip code. Many external chips
add a few GPIOs as secondary functionality (such as MFD drivers) and platform
code frequently needs to closely integrate GPIO and IRQ support.
This is placed *early* in the build/link sequence since it's common for other
drivers to depend on GPIOs to do their work, so they must be initialized early
in the device_initcall() sequence.
