sdhci: implement CAP_CLOCK_BASE_BROKEN quirk

Some hosts (e.g.  as found in CNS3xxx SOCs) report wrong value in
CLOCK_BASE capability field, and currently there is no way to force the
SDHCI core to use the platform-provided base clock value.

This patch implements CAP_CLOCK_BASE_BROKEN quirk.  When enabled, the
SDHCI core will always use base clock frequency provided by the platform.
