[PATCH 5.10 87/98] mmc: sdhci-iproc: Set SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN on BCM2711

From: Sasha Levin

From: Nicolas Saenz Julienne <nsaenz@xxxxxxxxxx>

[ Upstream commit 419dd626e357e89fc9c4e3863592c8b38cfe1571 ]

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.
