[008/244] omap-serial: Allow IXON and IXOFF to be disabled.

[Greg KH]

3.0-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Nick Pelly <npelly@xxxxxxxxxx>

commit b280a97d1caf6fe1d38b51ebb31219391f5ad1a0 upstream.

Fixes logic bug that software flow control cannot be disabled, because
serial_omap_configure_xonxoff() is not called if both IXON and IXOFF bits
are cleared.
