atmel_serial: RS485: receiving enabled when sending data

By default the atmel_serial driver in RS485 mode disables receiving data until
all data in the send buffer has been sent. This flag allows to receive data
even whilst sending data.

(although when we have people having a serious meta discussion about four
 spaces, or a tab or neither rather than functionality I despair)

We could ignore it, but then we end up with code being randomly
formatted throughout files, which makes it _more_ likely that the
code will be misread later.  That in turn makes the chances of
bugs introduced more likely in the future.

It also encourages 'cleanup' patches further down the line, so more
churn - which is something that Linus has been complaining about,
particularly in regard to ARM stuff.

It's far better to get things right the first time round than have
to keep touching stuff time and time again - either because of
cleanup patches or because of subtle bugs introduced by misreading
the code.
