[PATCH 2/7] mmc: sdhci: fix programmable clock config from preset value

[MichaÅ MirosÅaw]

When host controller uses programmable clock presets but doesn't
advertise programmable clock support, we can only guess what frequency
it generates. Let's at least return correct SDHCI_PROG_CLOCK_MODE bit
value in this case.
