powerpc/85xx: fixup flexcan device tree clock-frequency 

Make the fixup matchable with dts and kernel.  Update the compatible from
"fsl,flexcan-v1.0" to "fsl,p1010-flexcan" and Change the "clock-freq"
property to "clock-frequency".  We also change flexcan frequency from
CCB-clock to CCB-clock/2 according to P1010 spec.

We now keep the old interfaces to make previous kernel work. They should
be removed in the future.
