mips DMA buildbot fixes

[Christoph Hellwig]

Hi Thomas,

this series fixes a few trivial warnings in the mips DMA code that the
buildbot keeps complaining about.

[PATCH 1/3] MIPS: pci-ar2315: include <linux/dma-direct.h> for phys_to_dma

[Christoph Hellwig]

Ensure this file has a prototype for phys_to_dma and dma_to_phys.

[PATCH 3/3] MIPS: force CONFIG_PCI to on for IP27 and IP30

[Christoph Hellwig]

These are PCI based systems, so not enabling the support is rather
pointless.  Additionally the random configѕ generated by the build bot
for IP27 and IP30 builds without PCI fail to buіld.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
