arm64: dts: rockchip: Add missing everest,es8388 supplies to rk3399-roc-pc-plus

Browse Source 
The regulator supplies for everest,es8388 audio codec are missing and
are required. Add them based on the schematics found here:

https://personalbsd.org/download/Documents/SCH/ROC-RK3399-PC-PLUS-V20-20210809.pdf

With this, "regulator-always-on" should no longer be necessary for LDO5.
