mmc: sdio: ensure mmc_sdio_detect is powered

Browse source 
To prevent an erroneous removal of the card, make sure
the device is powered when it is mmc_sdio_detect()ed.

This is required since mmc_sdio_detect may be invoked
while the device is runtime suspended (e.g., MMC core
is rescanning when system comes out of suspend).
