This sdio card supports having its sdio clock shutdown.
It is also not using the SDIO IRQ, but rather uses a side gpio irq.

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.

Some cards have quirks valid for every platforms using current
platform quirk hooks leads to a lot of code and debug duplication.
So we inspire a bit from what exists in PCI subsystem and do our own
per vendorid/deviceid quirk. We still drop the complexity of the pci
quirk system (with special section tables, and so on).
That can be added later if needed.
