Benjamin Herrenschmidt 190de00538 [POWERPC] 4xx: Rework clock probing in boot wrapper
This reworks the boot wrapper library function that probes
the chip clocks. Better separate the base function that is
used on 440GX,SPe,EP,... from the uart fixups as those need
different device-tree path on different processors.

Also, rework the function itself based on the arch/ppc code
from Eugene Surovegin which I find more readable, and which
handles one more bypass case. Also handle the subtle difference
between 440EP/EPx and 440SPe/GX, on the former, PerClk is derived
from the PLB clock while on the later, it's derived from the OPB.
