Install a gpiolib driver supporting the on-chip gpios for single-core MSMs in the 7x00 family, including 7x00A, 7x25, 7x27, 7x30, 8x50, and 8x50a. As part of the ongoing effort to converge on a common code base, this driver is based on the Google-Android msmgpio driver, whose authors include Brian Swetland and Arve Hjønnevåg.
