arm64: dts: lg: Add missing PL011 "uartclk"

The PL011 IP has 2 clock inputs for UART core/baud and APB bus. The
LG131x SoCs are missing the core "uartclk". In this case, the Linux
driver uses single clock for both clock inputs. Let's assume that's how
the h/w is wired and make the DT reflect that.
