This is a USB-GPIO, USB-I2C and USB-SPI device. We add 4 drivers to support this device: a USB driver, a GPIO chip driver, a I2C controller driver and a SPI controller driver. --- v2: - ljca: remove reset command. - gpio/spi/i2c: add `default MFD_LJCA` in Kconfig. - gpio: add "select GPIOLIB_IRQCHIP" in Kconfig.
