[-mm patch] Remove ZONE_DMA remains from avr32

[Haavard Skinnemoen <hskinnemoen@atmel.com>]

Put all available lowmem in ZONE_NORMAL now that ZONE_DMA can be
disabled (which is the right thing to do on AVR32.)

Btw, 2.6.18-rc7-mm1 seems to boot on my board, but mdev (busybox's udev
replacement) seems to have a problem with symlinks so I don't have any
tty devices to log into. Using static /dev solves the problem for
now.
