Ola Jeppsson a4e7ebe47b Add burst test 
Add test for writes to same address. Apparently consecutive 64-bit
writes to the same address can turn into burst writes.

Test burst writes

https://github.com/parallella/oh/issues/37

Remembered that we have a long forgotten mode in the epiphany chip elink (not impemented in the fpga elink) that creates bursts when you write doubles to the same address. (F**K!) So the writes were likely coming in as bursts. Looks like the mailbox works fine when you write in "int"s (I tested it on the board with consecutive) (see "mailbox_test" in elink/sw0)
