ide: add at91_ide driver
This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory Controller with Compact Flash True IDE Mode logic. Driver have to switch 8/16 bit bus width when accessing Task Tile or Data Register. Moreover some extra things need to be done when setting PIO mode. Only PIO mode is used, hardware have no DMA support. If interrupt line is connected through GPIO extra quirk is needed to cope with fake interrupts.
