The module branch is WiP but has stalled as I've had to work on other
stuff.  It still needs

1) Infrastructure within FW to load module via IPC command (I think
most relocation types are now processed). It should be able to process
.o files built with xtensa xt-cc or xtensa-gcc.

2) IPC commands for loading and unloading.

3) Driver support for new IPC ommands.
