gpio: Add driver for SPI serializers commit df6df93c8a73f6f9be38d4128fe25a5ee613d66c upstream. 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).
