[MIPS] Alchemy: fix PCI resource conflict
... by getting the PCI resources back into the 32-bit range -- there's no need therefore for CONFIG_RESOURCES_64BIT either. This makes Alchemy PCI work again while currently the kernel skips the bus scan. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
