[PATCH v2] serial: 8250_lpss: Unconditionally set PCI master for Quark

[Jan Kiszka]

MSI needs it as well.

Should have no practical impact, though, as DMA is always available on
the Quark. But given the few users of pci_alloc_irq_vectors so far, this
incorrect pattern may spread otherwise.

Just a repost, no code change - missed to do this with Andy's tag after
the review.
