I currently (patch v8) disable gating for all SDIO cards,
but I guess there are two approaches to cases where you'd
like to enable it:

- Card (including SDIO device) whitelisting.

- Host whitelisting - for the case where as gateable SDIO
  device is soldered to the bus.

The first looks like big-ish so would be a separate patch, but a
host flag for the latter like MMC_CAP_GATE_SDIO can easily be
folded into a v10 of this patch.

Is that desireable?
