firewire: IEEE 1394 (FireWire) support should depend on HAS_DMA
Commit b3d681a4fc108f9653bbb44e4f4e72db2b8a5734 ("firewire: Use
COMPILE_TEST for build testing") added COMPILE_TEST as an alternative
dependency for the purpose of build testing the firewire core.
However, this bypasses all other implicit dependencies assumed by PCI,
like HAS_DMA.
If NO_DMA=y:
drivers/built-in.o: In function `fw_iso_buffer_destroy':
(.text+0x36a096): undefined reference to `dma_unmap_page'

Add an explicit dependency on HAS_DMA to fix this.
