Subject: [PATCH 3/3] mmc: sdhci-iproc: Set SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN on BCM2711

The controller doesn't seem to pick-up on clock changes, so set the
SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN flag to query the clock frequency
directly from the clock.

Fixes: f84e411c85be ("mmc: sdhci-iproc: Add support for emmc2 of the BCM2711")
