Subject: i2c: designware: Print clock freq on invalid clock freq error
Git-commit: 22acc37b8681461707a3fc73505af808f9af8260
Patch-mainline: v4.13-rc5
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539
When we refuse to probe due to an invalid clock frequency, log
the frequency which is causing this error.
