Update the DaVinci DM6446 boards to use the new convention for CONFIG_SYS_NS16550_REG_SIZE ... the size hasn't changed from the original 4 bytes, but these chips are little-endian. (Resolves a regression added recently by the include/ns16550.h patch to "Unify structure declaration for registers". The code previously worked just fine because the registers were accessed as host-endian words, not as bytes.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
