Commit Message

For UART devices the M_GP_LENGTH is the TX word count. For other
devices this is the transaction word count.

For UART devices the S_GP_LENGTH is the RX word count.

The IRQ_EN set/clear registers allow you to set or clear bits in the
IRQ_EN register without needing a read-modify-write.

Acked-by: Bjorn Andersson <andersson@kernel.org>
Signed-off-by: Douglas Anderson <dianders@chromium.org>
---
Since these new definitions are used in the future UART patches and
Bjorn has Acked them, I'd expect them to go through the same tree as
the UART patches that need them.
