d5edb1ca88 Fixing priority on etx_arbiter 
- don't do a combinatorial loopback on wait in a primitive cell, just bad practice...
- changed priority to give readback priority over read, safer?

ddfeebd33f Cleaning up read response logic 
- Bypass path was ugly! Always try to go through the same logic path as much as possible.
- Note: when MMU is enabled, you need to put in entry for read return (ie 810)

7e49b29a79 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.

3ce9b41726 Working mailbox! 
- Gating mailbox_not empty with irq_en. bit [28] of RXCFG
- Changing elink output interrupt to "or" of not_empty and full
- Adding mailbox status register (mostly for debug)
- Moving register addresses to make space for mailbox status register
- Fixing wrappers for DV
- Updating README docs with new register map
- Removing mailbox from RX status reg. Doesn't belong there, should be coupled with mailbox for modularity.
