OMAP2/3: mmc-twl4030: Free up MMC regulators while cleaning up
twl_mmc_cleanup() must free up the regulators that were
allocated by twl_mmc_late_init().
This eliminates the below error when 'omap_hsmmc' module is
repeatedly loaded and unloaded.
"sysfs: cannot create duplicate filename '/devices/platform
/mmci-omap-hs.0/microamps_requested_vmmc'"
