Revert "powerpc/83xx: gianfar_ptp: select 1588 clock source through dts file"
This reverts commit 894116bd0e9b7749a0c4b6c62dec13c2a0ccef68.
I applied the wrong version of this patch, correct
version coming up.

Here is how to figure good values:
- TimerOsc = selected reference clock MHz
+ TimerOsc = system clock MHz
tclk_period = desired clock period nanoseconds
NominalFreq = 1000 / tclk_period MHz
FreqDivRatio = TimerOsc / NominalFreq (must be greater that 1.0)
