dma-direct: exclude dma_direct_map_resource from the min_low_pfn check
The valid memory address check in dma_capable only makes sense when mapping
normal memory, not when using dma_map_resource to map a device resource.
Add a new boolean argument to dma_capable to exclude that check for the
dma_map_resource case.
Fixes: b12d66278dd6 ("dma-direct: check for overflows on 32 bit DMA addresses")
