mmc: add MMC_QUIRK_BROKEN_CLK_GATING

Some sdio card are not following sdio standard, and do not work
when the sdio bus's clock is gated.

To keep functionnality for all legacy driver, we turn this quirk on
for every sdio card.
Drivers needs to disable the quirk manually when someone verifies that
their supported card works with clock gating.
