Add ADMA2 support in omap hsmmc driver. It's not added as a dma engine since ADMA2 is only implemented in HSMMC. Though this doesn't improve the throughput with high speed cards, around 25% improvement is seen with HS200 card. HS200 support is not yet added in OMAP HSMMC since it has dependency with IODelay driver which is not yet upstreamed. Tested MMC1 and MMC2 in DRA7 (dra72-evm, dra7-evm) and OMAP5 (omap5-uevm). Also tested having rootfs in MMC1 in DRA7, OMAP5, OMAP4 and OMAP3.
