This series introduces uart_port_tx() + uart_port_tx_limited() TX
helpers. See PATCH 8/10 for the details. Comments welcome.

First the series performs simple cleanups, so that the later patches are
easier to follow.

Then it switches drivers to use them. First, to uart_port_tx() in 9/10
and then uart_port_tx_limited() in 10/10.

The diffstat of patches 9+10 is as follows:
 26 files changed, 145 insertions(+), 740 deletions(-)
which appears to be nice.

I've queued up the first 7 patches here, as they were the preparation /
cleanup patches and deserved to go in no matter what.
