Make the ppc32 pcibios_alloc_controller take a device node to match
the ppc64 prototypes and have it set arch_data.
Signed-off-by: NKumar Gala <galak@kernel.crashing.org>

Make the pci_controller struct use global_number for the PHB domain number
instead of index to match what ppc64 does and reuse its pci_domain_nr code.

Introduced a pci-common.c to handle shared code between ppc32 & ppc64.

Some code looks can be configured to be built without
PCI support, but does not work properly.

Implement deep-sleep on MPC52xx.
SDRAM is put into self-refresh with help of SRAM code
(alternatives would be code in FLASH, I-cache).
Interrupt code must also not be in SDRAM, so put it
in I-cache.
MPC52xx core is static, so contents will remain intact even
with clocks turned off.

This reverts commit 9414715a,
at Olaf Hering's request:

> Paul, please discard this patch. The optional graphics card may have
> also device_type 'serial' if it is in VGA mode.
> I will send an updated patch later.

These got added recently.

Efika boards have to be booted with console=ttyPSC0 unless there is a
graphics card plugged in. Detect if the firmware stdout is the serial
connector.

The efika platform used three files efika-pci.c efika-setup.c and
a 2 line efika.h to link the two. The total of code in those is
really not much and therefore, I think they're better merged
in a single file.

There is absolutely _no_code_change_ at all, just merged the files.
