[PATCH v1 6/6] arm64: dts: rockchip: describe RK3308 codec detection resources

[Xing Zheng]

Describe the detection GRF phandle and the codec and headphone
interrupts for the internal audio codec. Name the interrupts so
consumers can identify the revision-B/C headphone detector without
depending on resource indices.

Keep board audio routes and external amplifier GPIOs out of the SoC
description.
