mmc/dwmmc: modify FIFO threshold only if value explicitly set

If platform provides "host->fifoth_val" it will be used for
initialization of DWMCI_FIFOTH register. Otherwise default value will be
used.

This implementation allows:
 * escape unclear and recursive calculations that are currently in use
 * use whatever custom value for DWMCI_FIFOTH initialization if any
particular SoC requires it
