Could we have an architecture discussion about how this is supposed to be done
and a picture please !
(a pointer to good working code would be nice)
On brownstone the SDIO 8787 power is supplied by a ldo which is dedicated to
the internal SDIO chip.

With regulator vsdio, sdio client power on/off could be executed by
mmc_power_up/down
