EDMA code.
* create a new TX EDMA descriptor struct to represent TX EDMA descriptors
when doing debugging;
* implement an EDMA printing function which:
+ hardcodes the TX map size to 4 for now;
+ correctly prints out the number of segments - there's one descriptor
for up to 4 buffers (segments), not one for each segment;
+ print out 4 DS buffer and len pointers;
+ print out the correct number of DWORDs in the TX descriptor.
TODO:
* Remove all of the hard-coded stuff. Ew.
