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.
