misc: gehc-achc: new driver
General Electric Healthcare's PPD has a secondary processor from NXP's Kinetis K20 series. That device has two SPI chip selects: The main interface's behaviour depends on the loaded firmware and is currently unused. The secondary interface can be used to update the firmware using EzPort protocol. This is implemented by this driver using the kernel's firmware API. The firmware is being flashed into non-volatile flash memory, so it is enough to flash it once and not on every boot. Flashing will wear the flash memory (it has a life time of at least 10k programming cycles). At the same time only occasional FW updates are expected (like e.g. a BIOS update). Thus the firmware update is triggered via sysfs instead of doing it in the driver's probe routine like many other drivers.
