[PATCH] ls1b200: dts: add serials and nand nodes

add all serials and sort them by base address.
 UART0_1, UART0_2, UART0_3 renamed to
 serial6, serial7, serial8.
 UART1_1, UART1_2, UART1_3 renamed to
 serial9, serial10, serial11.

because the nand and pll share the some base
address, so add it as well.
