mmc: sdhci: Always pass clock request value zero to set_clock host op
To allow the set_clock host op to disable the SDCLK source when not needed, always call the host op when the requested clock speed is zero. Do this even if host->clock already equals zero, because the SDHCI driver may set that value (without calling the host op) to force an update at the next (non-zero-speed) call.
