when rebasing patches on top of Greg's tty-next,
it looks like automerge broke a few things which
I didn't catch (for whatever reason I didn't
have OMAP Serial enabled on .config) so I ended
up breaking the build on Greg's tty-next branch.

Fix the breakage by re-adding the three missing
members on struct uart_omap_port.

Hi Greg,

I just fetched your tree again and rebased again just to
make sure. Everything is fine here, let me know if it
still applies with fuzz.

cheers

Something is still wrong with omap-serial in tty-next. It now
compiles and works for the legacy non-devicetree case, but with
device tree booting there's now regression during boot:
