Add driver for Intel La Jolla Cove Adapter (LJCA) device.
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.

---
v6:
 - ljca: split LJCA USB driver into two commits: USB part and API part.
 - gpio/i2c/spi: use auxiliary bus for sub-module device enumeration instead of MFD.
 - move document patch for LJCA sysfs entry to the 3th patch of this patch series.
 - ljca: fix potential race condition when wait response timeout.
 - ljca: use devm_kzalloc to malloc ljca device struct. 

v5:
 - move ljca.h from drivers/include/mfd to drivers/include/usb.
 - ljca: fix a potential memory leak issue.
 - add a blank line before return to adust to kernel code style.
 - ljca: sysfs: split "cmd" to "ljca_dfu" and "ljca_trace_level".

v4:
 - move ljca.c from drivers/mfd to drivers/usb/misc folder.
 - fix index warning in sysfs-bus-devices-ljca.

v3:
 - spi: make ljca_spi_transfer inline and fix an endian issue.

v2:
 - ljca: remove reset command.
 - gpio/spi/i2c: add `default MFD_LJCA` in Kconfig.
 - gpio: add "select GPIOLIB_IRQCHIP" in Kconfig.

Ye Xiang (6):
  usb: Add support for Intel LJCA device
  usb: ljca: Add transport interfaces for sub-module drivers
  Documentation: Add ABI doc for attributes of LJCA device
  gpio: Add support for Intel LJCA USB GPIO driver
  i2c: Add support for Intel LJCA USB I2C driver
  spi: Add support for Intel LJCA USB SPI driver
