[PowerPC] Make cpu frequency detection endian-independent

On ibm,extended-clock-frequency, ensure we be64toh() the value.

On clock-frequency, remove the right-shifting hack (which was needed due to
reading a 32 bit value into a 64 bit variable) and switch to OF_getencprop()
for reading (which will handle endian conversion internally.)
