mmc: quirks: enable clock gating for AR6004 card
This patch whitelists the AR6004 card for clock-gating.
The controller supports asynchronous interrupt functionality
which enables to receive interrupts from the card when clocks
are off. Hence, clocks can be turned off when idle.
This patch whitelists the card, to let the clock-gating
framework gate the clock during idle time.
