Subject: IXP4xx: Fix DMA masks.
X-Git-Tag: v3.15-rc1~81^2~4

IXP4xx: Fix DMA masks.

Now, devices will have 32-bit default DMA masks (0xFFFFFFFF) as per DMA API.

Fixes:
$ ifconfig eth0 up
net eth0: coherent DMA mask is unset

$ ifconfig hdlc0 up
net hdlc0: coherent DMA mask is unset

Also fixes a cosmetic off-by-one bug which caused DMA transfers ending exactly
on the 64 MiB boundary to go through dmabounce unnecessarily.
