gpio: Add support for Intel LJCA USB GPIO driver

This patch implements the GPIO function of Intel USB-I2C/GPIO/SPI adapter
device named "La Jolla Cove Adapter" (LJCA). It communicate with LJCA
GPIO module with specific protocol through interfaces exported by LJCA USB
driver.

Select this option to enable GPIO driver for the INTEL
La Jolla Cove Adapter (LJCA) board.
This driver can also be built as a module. If so, the module
will be called gpio-ljca.
