arm926ejs: 8-byte align stack to avoid LDRD/STRD problems
U-boot for Marvell Kirkwood boards no longer work after the EABI changes introduced in commit f772acf8a584067033eff1e231fcd1fb3a00d3d9. This turns out to be caused by a stack alignment issue. The armv5te instructions ldrd/strd instructions require 8-byte alignment to work properly (otherwise undefined behavior). Tested on an OpenRD base board, where both printouts and ubifs stuff now works. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
