Add burst test
...
Add test for writes to same address. Apparently consecutive 64-bit
writes to the same address can turn into burst writes.
From:
https://github.com/parallella/oh/issues/37
Andreas:
> 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)

Moving tests for idelay, mailbox, timeout from epiphany-examples
...
-Idea is to create complete packages
-All hardware modules should be complete, separation of tasks/sources can drive 10x in dev cost.

Removing reset sequence from access utility
...
- Responsibility of application
- Makes no sense resettting device after each write/read..
