Patch from Lennert Buytenhek
The enp2611 version of the ixp2000 netdev driver needs to be able to
access a number of on-board peripherals. ioremap() is not suitable
for this, as that will cause XCB=000 mappings to be done, which will
make the cpu susceptible to crashing on ixp2400 erratum #66. Properly
aligned iotable mappings with MT_IXP2000_DEVICE will cause section
mappings with XCB=101 to be done, which is safe.
