The Firefly-RK3399 DeviceTree (`arch/arm64/boot/dts/rockchip/rk3399-firefly.dts`) defines a `simple-audio-card` device which selects a `realtek,rt5640` codec. This codec however is inaccessible in the kernel configuration (`SND_SOC_RT5640`) and thus cannot be used. This patch adds a new configuration option named `SND_SOC_ROCKCHIP_RT5640` which selects `SND_SOC_RT5640` and `SND_SIMPLE_CARD`, but does nothing else. It enables `SND_SIMPLE_CARD`, because that's what the Firefly has. I'm not sure if there are Rockchip products which need a different sound card driver with RT5640.
