atmel-mci: unified Atmel MCI drivers (AVR32 & AT91)
Unification of the atmel-mci driver to support the AT91 processors MCI
interface. The atmel-mci driver currently supports the AVR32 and this
patch adds AT91 support.
Add read/write proof selection switch dependent on chip availability of
this feature.
To use this new driver on a at91 the platform driver for your board needs
to be updated.
