Issue 883: Port AESS (ABE) driver to current kernel

Reported by Michael Mrozek, Jun 14, 2018

Right now, the AESS driver is not working.
This is a driver that enables hardware support for mixing, 
converting, etc. audio streams.

Without it, the CPU has to do everything, which is a horrible waste 
of CPU power.

Andrej started to work on this, but the current status is unknown:

I can work on it as I'm familiar with kernel sound subsystem.

A new version is available which seems to work on OMAP5 but breaks 
boot process on Pandaboard-ES. It even makes the Pandaboard reboot.

Has become worse with v5.3-rc1 because kernel APIs have changed and 
some more code had to be disabled.
