ARM: kirkwood: fdt: define uart[01] as disabled, enable uart0
Define both uarts in kirkwood.dtsi as they are common to all kirkwood
SoCs. Each board may enable all or none of them, so they are disabled
by default. uart0 is enabled for the dreamplug.
tclk can vary for each board, so we leave it undefined in the kirkwood
dtsi. Each board can then set it as appropriate when enabling the uart.
