For sdhci based drivers, it's better to parse their host specific
device tree properties in their host's driver (sdhci-xxx.c) rather
than in the shared sdhci platform driver (sdhci-pltfm.c).
Otherwise function sdhci_get_of_property need to parse every host's
private dt property and will be bigger and bigger.
This patch add a function of_get_property in sdhci_ops to parse host
specific device tree property.
