clk: bcm2835: Limit PCM clock to OSC and PLLD_PER

It is unwise to use sources other than the oscillator and PLLD_PER for
the PCM peripheral (and perhaps others - TBD) because their rate can
change and they may even be switched off, so explicitly restrict the
choice using dummy entries in the list of potential parents (item index
is significant).
