[U-Boot] [PATCH] HACK: fix return value of serial_assign to get printfs working again

[Allen Martin]

This reverts a recent change to serial_assign() that broke printfs on
tegra.  I don't think this is the real fix, but I'm just putting this
out for others who want to test tegra patches for the other
regressions.
