Not sure about WIFI, but serial seems already enabled:
CONFIG_SERIAL_AMBA_PL011=y
CONFIG_SERIAL_AMBA_PL011_CONSOLE=y
arch/arm64/boot/dts/hisilicon/hi6220.dtsi:
uart0: uart@f8015000 { /* console */
compatible = "arm,pl011", "arm,primecell";
reg = <0x0 0xf8015000 0x0 0x1000>;
interrupts = <GIC_SPI 36 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&ao_ctrl HI6220_UART0_PCLK>,
