arm64: dts: rockchip: fix audio-supply for Rock Pi 4
stable inclusion from stable-v5.10.88 commit 24983f750881b57f7476c51a3d07b08e017f425c bugzilla: 186058 https://gitee.com/openeuler/kernel/issues/I4QW6A Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=24983f750881b57f7476c51a3d07b08e017f425c -------------------------------- [ Upstream commit 8240e87f ] As stated in the schematics [1] and [2] P5 the APIO5 domain is supplied by RK808-D Buck4, which in our case vcc1v8_codec - i.e. a 1.8 V regulator. Currently only white noise comes from the ES8316's output, which - for whatever reason - came up only after the the correct switch from i2s0_8ch_bus to i2s0_2ch_bus for i2s0's pinctrl was done. Fix this by setting the correct regulator for audio-supply.
