arm64: dts: qcom: acer-aspire1: Add embedded controller

The laptop contains an embedded controller that provides a set of
features:

- Battery and charger monitoring
- USB Type-C DP alt mode HPD monitoring
- Lid status detection
- Small amount of keyboard configuration*

[*] The keyboard is handled by the same EC but it has a dedicated i2c
bus and is already enabled. This port only provides fn key behavior
configuration.

Add the EC to the device tree and describe the relationship between the
EC-managed type-c port and the SoC DisplayPort.

arm64: dts: qcom: acer-aspire1: Add sound

This laptop has two i2s speakers; an i2s audio codec for the headset
jack; two DMIC microphones in the lid and the displayport audio channel.

This commit adds the audio node that describes all of the above with the
exception of the DMICs that require in-SoC digital codec to be brought
up, which will be done later.

Note that the displayport channel is connected here for completeness,
but the displayport can't be used yet since the HPD signal is created by
the embedded controller, which will be added later.

arm64: dts: qcom: acer-aspire1: Correct audio codec definition

When initially added, a mistake was made in the definition of the codec.

Despite the fact that the DMIC line is connected on the side of the
codec chip, and relevant passive components, including 0-ohm resistors
connecting the dmics, are present, the dmic line is still cut in
another place on the board, which was overlooked.

Correct this by replacing the dmic configuration with a comment
describing this hardware detail.

While at it, also add missing regulators definitions. This is not a
functional change as all the relevant regulators were already added via
the other rail supplies.

arm64: dts: qcom: acer-aspire1: Enable RTC

pm6150 has a read-only RTC that can be used to keep the time with some
extra userspace tools. Enable it.

arm64: dts: qcom: sc7180-aspire1: use generic ADC channel node names

ADC channel node names were changed to require generic 'channel'. The
user-visible part is defined via label.

sc7180-acer-aspire1.dtb: adc@3100: 'charger-thermistor@4f', 'thermistor@4e' do not match any of the regexes: '^channel@[0-9a-f]+$', 'pinctrl-[0-9]+'

arm64: dts: qcom: sc7180: rename labels for DSI nodes

Currently in board files MDSS and DSI nodes stay apart, because labels
for DSI nodes do not have the mdss_ prefix. It was found that grouping
all display-related notes is more useful.

To keep all display-related nodes close in the board files, change DSI
node labels from dsi_* to mdss_dsi_*.

arm64: dts: qcom: Add Acer Aspire 1

Acer Aspire 1 is a WoA laptop based on Snapdragon 7c gen1 platform.

The laptop design is similar to trogdor in the choice of primary
components but the specifics on usage of those differ slightly.

Add the devicetree for the laptop with support for most of the
hardware present.
