[PATCH v1 10/23] arm: dts: layerscape: nbxv3: enable UART0..UART3

&uart0 (LX2160ARM UART1, MMIO 0x021c0000) is the console. The
remaining three (&uart1..&uart3) are available for applications
at the U-Boot prompt.

Numbering note: the LX2160A has four PL011 UARTs on chip. The
reference manual labels them 1 indexed (UART1..UART4); the device
tree is 0 indexed (&uart0..&uart3).
The mapping is constant across the family:

 - &uart0   LX2160ARM UART1   MMIO 0x021c0000   (console)
 - &uart1   LX2160ARM UART2   MMIO 0x021d0000
 - &uart2   LX2160ARM UART3   MMIO 0x021e0000
 - &uart3   LX2160ARM UART4   MMIO 0x021f0000

TF-A also uses &uart0 for its own boot log.

U-Boot console is at 115200 8N1.
