[PATCH net-2.6] starfire: Fix dma_addr_t size test for MIPS

[Ben Hutchings <ben@decadent.org.uk>]

Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed
that the preprocessor condition used to find the size of dma_addr_t
yielded the wrong result for some architectures and configurations.
This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet
another case to the condition.  However, 64-bit MIPS configurations
are not detected reliably either.

This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that
isn't yet defined everywhere it should be.

Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
---
The MIPS conditions are changed to match those Tomonori specified for
CONFIG_ARCH_DMA_ADDR_T_64BIT.

Please change the condition to defined(CONFIG_ARCH_DMA_ADDR_T_64BIT) in
net-next-2.6.  I leave it up to you to decide when to make that change.
(Simply applying a patch to net-next-2.6 now will result in a later
merge conflict and breakage for those two architectures.)

Ben.
