gpio: Add driver for SPI serializers
Add generic parallel-in/serial-out shift register GPIO driver.
This includes SPI compatible devices like SN74165 serial-out shift
registers and the SN65HVS88x series of industrial serializers that can
be read over the SPI bus and used for GPI (General Purpose Input).
