ARM: OMAP3: mmc-twl4030 voltage cleanup
Correct twl4030 MMC power switching: fix voltage ranges reported for each slot, and handle them fully. Lies corrected: - MMC-1 doesn't support the 2.6-2.7 Volt range - MMC-2 can't normally support anything except 1.8V Omissions corrected - MMC-1 *does* handle the 2.8-2.9 Volt range - MMC-2 can handle 2.5-3.2 Volt cards, given a transceiver Add transciever support for MMC-2; enable it for Overo and Pandora. (Depends on something else to have set up pinmuxing for control signals instead of as MMC2_DAT4..7 pins.) Also shrink twl4030_hsmmc_info a smidgeon ... padding is all gone.
