ion: use correct section map size for LPAE



Use correct section map size for LPAE. At present ion use
CONFIG_IOMMU_IO_PGTABLE_ARMV7S to determine whether to use LPAE or short
descriptor section size.  This is insufficient. Check for CONFIG_64bit and
CONFIG_LPAE as well to decide correct section size.
