ns16550: add generic binding to unify the drivers

The key difference between these drivers is the way to get
input clock frequency. With this unified approach, fixed clock
frequency should be extracted from "clock-frequency" property of
device tree blob. If this property is not available, the macro
CONFIG_SYS_NS16550_CLK will be used. It can be a constant or a

rockchip: Turn on CONFIG_DEBUG_UART_NS16550 in defconfigs

No UART driver was specified in defconfig, thus
DEBUG_UART_ALTERA_JTAGUART was incorrectly selected by default since
commit 220e8021af96741bd7149ca9895e1f0c8a38d0bb added a new Altera UART
driver.
