ARM: ixp4xx: avoid use of PCIBIOS_MIN_MEM in io.h
When using CONFIG_IXP4XX_INDIRECT_PCI, we run into a recursive header file dependency between mach/io.h and asm/pci.h, resulting in a build failure: mach-ixp4xx/include/mach/io.h: In function 'is_pci_memory': mach-ixp4xx/include/mach/io.h:53:18: error: 'PCIBIOS_MIN_MEM' undeclared (first use in this function) return (addr >= PCIBIOS_MIN_MEM) && (addr <= 0x4FFFFFFF); ^ mach-ixp4xx/include/mach/io.h:53:18: note: each undeclared identifier is reported only once for each function it appears in We can work around this by referencing the pcibios_min_mem variable directly through an extern declaration, rather than using the macro.
