Subject: [PATCH 1/2] ASoC: dt-bindings: everest,es8328: Mark ES8388 compatible with ES8328

Based on Linux driver, the ES8388 looks fully compatible with ES8328.
One upstream DTS (ARM rk3288-rock2-square.dts) already uses ES8328
fallback, so mark the devices as compatible in the binding.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

ARM64 Rockchip DTS use only single everest,es8388 compatible, so this
will trigger dtbs_check warnings which I will fix in separate patchset.

No ABI break/impact expected.

Expected dtbs_check warnings:

arm64/boot/dts/rockchip/rk3399-roc-pc-plus.dtb: es8388@11: compatible: 'oneOf' conditional failed, one must be fixed:
  ['everest,es8388'] is too short
  'everest,es8388' is not one of ['everest,es8328']
