atmel-mci: Platform code for supporting multiple mmc slots
Add the necessary platform infrastructure to support multiple mmc/sdcard slots all at once through a single controller. Currently, the driver will use the first valid slot it finds and stick with that, but later patches will add support for switching between several slots on the fly. Extend the platform data structure with per-slot information: MMC/SDcard bus width and card detect/write protect pins. This will affect the pin muxing as well as the capabilities announced to the mmc core. Note that board code is now required to supply a mci_platform_data struct to at32_add_device_mci().
