ppc_md.calibrate_decr() is a mandatory item. Its nullity is never
checked so it must be non null on all platforms.
Most platforms define generic_calibrate_decr() as their
ppc_md.calibrate_decr(). Have time_init() call
generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL,
and remove default assignment from all machines.

Factor out the common codes of setup arch functions to a separate
function. It does make no sense to print a board specific info
in setup arch functions, so use a more general one.
For ASP8347E board, there is no pci device node. So it is safe to
invoke mpc83xx_setup_pci() in its setup arch function even there is
no such invocation in its original setup arch function.

This converts all the 32-bit platforms to use the expanded device-tree
which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel
didn't rely on platform initializations to setup the MMU since it
sets it up entirely before probe_machine() so the move has comparatively
less consequences though it's a bigger patch.

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.

Commit a4f740cf, "of/flattree: Add of_flat_dt_match() helper function"
introduced build failures in arch/powerpc/platform/83xx by mistyping
'static' as 'struct' in the compatible string list, and omitting a few
semicolons. This patch fixes it.

This patch adds of_flat_dt_match() which tests a node for
compatibility with a list of values and converts the relevant powerpc
platform code to use it. This approach simplifies the board support
code a bit.

Also, remove of_device_is_avaliable() check from the mpc837x_mds.c
