dm: mmc: Add a library function to parse generic dt binding

Browse Source 
Add a new function to parse host controller dt node and
set mmc_config. This function can be used by mmc controller
drivers to set the generic mmc_config.
This function can be extended to set other UHS mode caps
once UHS mode support is added.
