MMC fixes for 3.5-rc7: 

- Revert a patch that made failing to select power class fatal;
    it turns out that it fails non-fatally on Tegra boards.
    Regression against 3.5-rc1.
  - Add the IRQF_ONESHOT flag to the cd-gpio driver, which turned
    into a regression in 3.5-rc1 when IRQF_ONESHOT became required
    for threaded IRQs with no handler.
