[LEDE-DEV] [PATCH v1 4/4] ramips/RT5350F-OLINUXINO(-EVB) dts: enable ttyS1

 The RT5350F's second UART pins are available on the base module and on
the EVB as well, so enable it in the device tree.
 In order to keep the origian serial port numbering (ttyS0 is the serial
console), aliases added for the UART devices.
