[POWERPC] prpmc2800: Fix frequencies in prpmc2800.dts

After the conversion to dts v1 format, seeing the frequencies
in decimal made it obvious that some of them had been
incorrectly truncated. This fixes them. Note that the PCI
frequency comes from a different source and is documented
as 66MHz, so it was left at 66000000.
