MMC fixes for 3.6-rc5:

Browse source 
- a firmware bug on several Samsung MoviNAND eMMC models causes
    permanent corruption on the device when secure erase and secure trim
    requests are made, so we disable those requests on these eMMC devices.
  - atmel-mci: fix a hang with some SD cards by waiting for not-busy flag.
  - dw_mmc: low-power mode breaks SDIO interrupts; fix PIO error handling;
    fix handling of error interrupts.
  - mxs-mmc: fix deadlocks; fix compile error due to dma.h arch change.
  - omap: fix broken PIO mode causing memory corruption.
  - sdhci-esdhc: fix card detection.
