[PATCH 04/11] rt2x00: Restrict DMA to 32-bit addresses.

[Ivo van Doorn <ivdoorn@gmail.com>]

From: Gertjan van Wingerde <gwingerde@kpnplanet.nl>

None of the rt2x00 PCI devices support 64-bit DMA addresses (they all only accept 32-bit
buffer addresses). Hence it makes no sense to try to enable 64-bit DMA addresses. Only
try to enable 32-bit DMA addresses.
