mmc: core: fix regression: set default clock gating delay to 0
A recent commit "mmc: core: Use delayed work in clock gating framework" (597dd9d79cfbbb1) introduced a default 200ms delay before clock gating actually takes place. This means that every time an MMC interface becomes idle it first stays on for 200ms before gating its clock. This leads to increased power consumption and is therefore a clear regression. This patch restores the original behaviour by setting the default delay to 0. Users prioritising throughput over power efficiency can still modify the delay via sysfs.
