Nearly all mpc83xx-based boards have a common piece of code - one that
loops over all pci/pcie bridges and registers them. Merge that code into
a special function common to all boards.

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.

On mpc83xx platform nearly all _init_IRQ functions look alike. They either
just setup ipic, or setup ipic and QE PIC. Separate this to special functions
to be either referenced from ppc_md, or called from board file.

It's possibly that we get an reset requestion when interrupts are disabled.
(For example an oops in an interrupt handler). Therefor, we can't call
ioremap in the reset function. Moving the ioremap of the registers we
need access to an arch_initcall helps the problem.
However we still have a window between boot and the arch_initcall in
which the register pointer will not be setup and thus we spin if the reset
function is called. If one needs to ensure even this case is covered, look
at use of the watchdog provided on 83xx to reset the processor.

Moved some code around so its usable by more systems than just
the MPC834x SYS.
