Jay Cornwall d5b4078072 Insert explicit memory fence before submitting doorbell
Ensure that the write index and ring buffer contents are visible
to the HW before sending the doorbell. The latter is a write-combined
MMIO store and must be ordered with prior cacehable non-MMIO stores.

Also be more explicit about memory semantics for doorbell stores.
