Subject: [PATCH 01/10] ARM: orion5x: Rename PCI_CONF_{REG,FUNC}() out of the way

orion5x defines PCI_CONF_REG() and PCI_CONF_FUNC() that are problematic
because PCI core is going to introduce defines with the same names.

Add ORION5X prefix to those defines to avoid name conflicts.

Note: as this is part of series that replaces the code in question
anyway, only bare minimum renaming is done and other similarly named
macros are not touched.
