Lukas Wunner c75289a7b7 serial: omap: Fix EFR write on RTS deassertion ...

commit 2a71de2f73 upstream.

Commit 348f9bb31c ("serial: omap: Fix RTS handling") sought to enable
auto RTS upon manual RTS assertion and disable it on deassertion.
However it seems the latter was done incorrectly, it clears all bits in
the Extended Features Register *except* auto RTS.
