gpio: add driver for basic memory-mapped GPIO controllers
The basic GPIO controllers may be found in various on-board FPGA and ASIC solutions that are used to control board's switches, LEDs, chip-selects, Ethernet/USB PHY power, etc. These controllers may not provide any means of pin setup (in/out/open drain). The driver supports: - 8/16/32/64 bits registers; - GPIO controllers with clear/set registers; - GPIO controllers with a single "data" register; - Big endian bits/GPIOs ordering (mostly used on PowerPC).
