sdhci-s3c: add support for the non standard minimal clock value
S3C SDHCI host controller can change the source for generating mmc clock.
By default host bus clock is used, what causes some problems on machines
with 133MHz bus, because the SDHCI divider cannot be as high get proper
clock value for identification mode. This is not a problem for the
controller, because it can generate lower frequencies from other clock
sources. This patch changes sdhci driver to use get_min_clock() call if
it has been provided.
This fixes the flood of the following warnings on Samsung S5PV210 SoCs:
mmc0: Minimum clock frequency too high for identification mode
