mpc83xx: Fix alternating tx error / tx buffer not ready bug in QE UEC
The problem is not gcc4 but the code itself. The BD_STATUS() macro can't
be used for busy-waiting since it strips the 'volatile' property from
the bd variable. gcc3 was working by pure luck.
This is a follow on patch to "Fix the UEC driver bug of QE"
