83xx board files have a lot of duplication in
*_declare_of_platform_devices() functions. Merge that into a single
function common to most of the boards.
The only leftover is mpc834x_itx.c board file which explicitly asks for
fsl,pq2pro-localbus, as corresponding bindings don't provide
"simple-bus" compatibility in localbus node.
