sunxi: Support UART4 on A80 (sun9i) as system console
* arch/arm/cpu/armv7/sunxi/board.c (gpio_init): Configure UART4
pins and function for CONFIG_CONS_INDEX == 5 (UART4) on
CONFIG_MACH_SUN9I
* include/configs/sunxi-common.h: Define CONFIG_SYS_NS16550_COM5
and CONFIG_SYS_NS16550_COM6 for CONFIG_MACH_SUN9I to refer to
UART4 and UART5, respectively. Define OF_STDOUT_PATH for
CONFIG_CONS_INDEX == 5 (UART4) on CONFIG_MACH_SUN9I
* arch/arm/include/asm/arch-sunxi/gpio.h (SUN9I_GPG_UART4): Define.
Validated against A80-Q7 module.
