If available voltages are not given, mmc_regulator_get_supply() function
returns 0 and mxcmmc driver doesn't set a value for ocr_avail mask.

In accordance with the comment in platform_data/mmc-mxcmmc.h,
fix it, assuming MMC_VDD_32_33 | MMC_VDD_33_34 as default value.

v2:
* Add test to check if mmc->ocr_avail is setted by mmc_regulator_get_supply().
This will prevent that it be overwritten unconditionally.
