[U-Boot] [PATCH] board_f.c: Insure gd->new_bootstage alignment

In reserve_bootstage(), in case size is odd, gd->new_bootstage
is not aligned. In bootstage_relocate(), the platform hangs when
getting access to data->record[i].name.
To avoid this issue, make gd->new_bootstage 16 byte aligned.

Fixes: ac9cd4805c8b ("bootstage: Correct relocation algorithm")
