ns16550: change reg-shift property default to zero
Change reg-shift property default to zero. When the integer property is missing, it should be taken as zero. This is consistent to Linux drivers/tty/serial/of_serial.c. The x86 and most powerpc use reg-shift of 0. Most others use reg-shift of 2. While reg-shift of 1 is rarely used.
