Currently it is not possible to use 'mmc-pwrseq-simple' property with this
driver because mmc_of_parse() is never called.

mmc_of_parse() calls mmc_pwrseq_alloc() that manages MMC power sequence.

Call the generic mmc_of_parse() so that we can use 'mmc-pwrseq-simple' to 
provide reset GPIO to the Wifi/BT chip.

Tested on a imx6sl-warp board.
