Kumar Gala dbf8471f52 [POWERPC] Merge ppc32 and ppc64 pcibios_alloc_controller() prototypes
Make the ppc32 pcibios_alloc_controller take a device node to match
the ppc64 prototypes and have it set arch_data.

Kumar Gala 5516b540e9 [POWERPC] Use global_number in ppc32 pci_controller
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.

Kumar Gala 7d52c7b0cd [POWERPC] Pass the pci_controller into pci_exclude_device
There are times that we need to know which controller we are on to decide
how to exclude devices properly.  We now pass the pci_controller that we
are going to use down to the pci_exclude_device function. This will
greatly simplify being able to exclude the PHBs in multiple controller
setups.

Kumar Gala 0e302a7044 [POWERPC] 52xx: Remove support for PCI bus_offset
The hose->bus_offset is only used for PCI config cycles and the 52xx PCI
config code doesn't actually ever set bus_offset to a non-zero value.

Kumar Gala 5ab9c4524d [POWERPC] Remove set_cfg_type for PCI indirect users that don't need it
The Freescale and Marvell PCI controllers dont require explicit setting for
type 1 config cycles.  They handle producing them by implicitly looking at the
bus, devfn.

The TSI108 and 52xx don't use the generic PCI indirect code and thus don't
bother with set_cfg_type.

Domen Puncer 2e1ee1f766 [POWERPC] mpc52xx suspend to deep-sleep
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.

Sylvain Munaut 9724b86f07 [POWERPC] Small cleanup of EFIKA platform
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.

Sylvain Munaut 5c334eed6e [POWERPC] 52xx: Don't use device_initcall to probe of_platform_bus
Using device_initcall makes it happen for every platform that
compiles this file in. This is really bad, for obvious reasons.

Instead, we use the .init field of the machine description. If
the platform needs the hook to do something specific it can provides
its own function and call mpc52xx_declare_of_platform_devices from
there. If not, the mpc52xx_declare_of_platform_devices function can
directly be used as the init hook.
