[U-Boot] [PATCH] Revert "Align global_data to a 16-byte boundary"

[Simon Glass]

This causes widespread breakage due to the operation of the low-level code
in crt0.S and cro0_64.S for ARM at least.

The fix is not complicated but it seems safer to revert this for now.

This reverts commit 2afddae07523f23f77acd066ad1719f53d289f98.
