On boot, pulseaudio looks for the sound cards' corresponding profile sets, and
uses a default configuration if none is found. This was causing pulseaudio to
take up to 5 seconds trying every possible default profile.
This commit fixes this by creating a specific profile set for each of the sound
cards on the ccimx6sbc so pulseaudio doesn't spend time trying different
profiles that don't apply to our platform. It also adds udev rules so
pulseaudio knows which configuration to load for each card.

The HDMI hotplug script required alsa-utils to be installed in order to work.
This commit avoids this by adding a recipe for a small binary that replaces
aplay in the script.

When hotplugging the HDMI cable after booting the target, pulseaudio doesn't
load the HDMI sink. This commit fixes this by adding a udev rule and a script
that prompts pulseaudio to detect the HDMI sound card and load its sink, as
well as making it the default one.
If alsa-utils is available, a faulty command is run to load the card without
any audio output. Otherwise, module-udev-detect is unloaded and reloaded.
This is based on commit fca507d316.

Some platforms, like ccimx6ulsbc, don't support jack detection
out of the box.
PulseAudio will mute the Headphones by default if it believes
there is no headphones jack plugged-in. With this patch we
tell it to preserve ALSA default value for the headphones
controls.

Using module-detect there are some audio reverb problems. Reverting that commit
will make pulseaudio use module-udev-detect again instead, which takes longer
to initialize but does not have that problem.
This reverts commit e021f738ee.

When module-alsa-sink is used, the audio is sometimes heard with
reverb. We will go back to module-udev-detect, so the functionality
introduced in the commit being reverted won't longer work.
This reverts commit fca507d316.

The ccimx6ul or ccardimx28 do not have hdmi interface, so do not install the
hdmi hotplug script.

This patch adds a udev rule and a script to detect HDMI hotplug and create
the HDMI audio pulseaudio sink if needed (that is, if the system was
booted with no HDMI cable plugged).

module-udev-detect blocks the sound interface on boot for about five
seconds while detecting the hardware. This patch removes it so that
module-detect is used instead, which uses static hardware detection and is
faster.
