HLC setup for generic devices and pin configuration

[mjlill]

Describe the bug
A clear and concise description of what the bug is.

1. The install setup improperly configures the /boot/config.txt to be for the AIY hat.
2. The HLC does not have hardware defined
3. The /etc/asound.conf has incorrect settings

To Reproduce
Steps to reproduce the behavior:
Install Alice or Alice satellite
/boot/config.txt should have set the
dtparam=audio=on
#dtoverlay=googlevoicehat-soundcard

/etc/asound.conf should have as content
pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "hw:0,0"
}
capture.pcm {
type plug
slave.pcm "hw:1,0"
}
}

/etc/systemd/system/hermesledcontrol.service
Suggest using --hardware=googleAIY as a default

Expected behavior
A clear and concise description of what you expected to happen.
Should work out of the box :)
Audio will be from 3.5mm Pi jack unless hdmi monitor is being used
sudo raspi-config item 7, audio, force 3.5mm should be set

Additional context
Add any other context about the problem here.
This has been tested using a PS#Eye web cam as a mic and also a generic usb audio adapter. This should make the most basic install work out of the box :)

Two possibilities:
a) Add a dummy device to HLC without LEDs
b) extend yaml so the user can define what pins should be used

implemented a) but more tests needed.
b) Might be configurable via myHome Sat/AliceCore DeviceType to keep the yaml simple

[philipp2310]

fixed with a)
will move this as enhancement for implementing b) later
