IXP4xx: Fix compilation failure with CONFIG_IXP4XX_INDIRECT_PCI.
Instead of including the heavy linux/mm.h for VMALLOC_START, test the addresses against PCI MIN and MAX addresses. Indirect PCI uses 1:1 mapping for MMIO space making this change possible. Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
