ES8328 and ES8388 codecs are I2C or SPI devices, thus they are
addressable on their bus and 'reg' property should be always provided.
Requiring 'reg' is pretty close to redundant, because the I2C and SPI
controller/bus bindings require it already, but the convention is to
mention 'reg' also in the device schemas.

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.

The ES8328/ES8388 audio codec is currently used in conjunction with
audio-graph-card to provide an endpoint for binding with the other side
of the audio link.
This is achieved via the 'port' property, which is not supported by the
binding:
rk3588s-indiedroid-nova.dtb: audio-codec@11: 'port' does not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/sound/everest,es8328.yaml#
Document the missing property.

Convert the binding to DT schema format. Note, that "IPVDD-supply"
got fixed to be "HPVDD-supply" during the conversion. This was
obviously a typo in the old binding. The old binding example, DT
files, chip datasheet and Linux driver use HPVDD.
