4487fd349b ETRAX-FS: Add support for DMA channel resets, needed for recent linux kernels.
* Correct numeric value for the RST state.
* Add emulation for reseting a DMA channel.
* Add a few sanity checks.
* Make it compile with debug enabled.

a8303d18e0 ETRAX: More DMA context level related fixes.
* When hitting EOL (end of list) at the data descriptor level, the DMA should mark the current context-descriptor as disabled and perform a context-store so software can see whats goin on.
* Context loads update RW_SAVED_DATA_BUF, data loads dont. This fixes an issue with ethernet bootstrapping.
* Reorder the logic for processing out channels to be more like the one for input channels.

* Support both ELF and kimage kernel images.
* Correct emulation of the DMA RW_DATA register.
