7c9503b838 SPARC: drivers: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

8885b7b637 PCI: Provide a default pcibios_update_irq()
Most architectures implement this in exactly the same way. Instead of
having each architecture duplicate this function, provide a single
implementation in the core and make it a weak symbol so that it can be
overridden on architectures where it is required.

3ddbebf878 PCI: Discard __init annotations for pci_fixup_irqs() and related functions
Remove the __init annotations in order to keep pci_fixup_irqs() around
after init (e.g. for hotplug). This requires the same change for the
implementation of pcibios_update_irq() on all architectures. While at
it, all __devinit annotations are removed as well, since they will be
useless now that HOTPLUG is always on.

c53a25543e sparc/PCI: factor out pcibios_setup()
The PCI core provides a generic pcibios_setup() routine.  Drop this
architecture-specific version in favor of that.

ac1edcc579 sparc/PCI: get rid of device resource fixups
Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

N.B. Leon apparently never uses initial BAR values, so it didn't matter
that we never fixed up the I/O resources from bus address to CPU addresses.

Other sparc uses pci_of_scan_bus(), which sets device resources directly
to CPU addresses, not bus addresses, so it didn't need pcibios_fixup_bus()
either.  But by telling the core about the offsets, we can nuke
pcibios_resource_to_bus().

2b591616ad sparc32, leon/PCI: convert to pci_scan_root_bus() for correct root bus resources
Convert from pci_scan_bus_parented() to pci_scan_root_bus() and remove root
bus resource fixups.  This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.

pci_scan_root_bus() also includes the pci_bus_add_devices() so we don't
need to do that separately.

7b64db608a sparc: add export.h to arch/sparc files as required
These files are only exporting symbols, so they don't need
the full module.h header file.  Previously they were getting
access to EXPORT_SYMBOL implicitly via overuse of module.h
from within other .h files, but that is being cleaned up.

26893c1368 sparc32,leon: added LEON-common low-level PCI routines
The LEON architecture does not have a BIOS or bootloader that
initializes PCI for us, instead Linux generic PCI layer is used
to set up resources and IRQ.
