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.
