ramips: HLK-RM04 - Enable GPIO14 for WPS button

The top half of UARTF on the HLK-RM04 is used for GPIO. mode 1 mode 2 RIN GPIO14 DSR_N GPIO13 DCD_N GPIO12 DTR_N GPIO11 RXD GPIO10 CTS_N GPIO09 TXD GPIO08 RTS_N GPIO07 This patch applies 3'b101 mode to UARTF: GPIO14 GPIO13 GPIO12 GPIO11 RXD CTS_N TXD RTS_N Because the base rt5350.dtsi file forces 3'b000 mode, remove the pin setting from this file and apply it directly to the files that inherit from it (WIZFI630A.dts and WT1520.dtsi). This change makes the rt5350.dtsi file consistent with the mt7620a.dtsi file.
