Cédric Le Goater b42ad43756 ppc/ppc405: QOM'ify CPU
Drop the use of ppc4xx_init() and duplicate a bit of code related to
clocks in the SoC realize routine. We will clean that up in the
following patches.

ppc_dcr_init() simply allocates default DCR handlers for the CPU. Maybe
this could be done in model initializer of the CPU families needing it.
