Hugo Villeneuve 5036d26337 serial: sc16is7xx: remove useless enable of enhanced features ...

commit 1c05bf6c02 upstream.

Commit 43c51bb573 ("sc16is7xx: make sure device is in suspend once
probed") permanently enabled access to the enhanced features in
sc16is7xx_probe(), and it is never disabled after that.

Therefore, remove re-enable of enhanced features in
sc16is7xx_set_baud(). This eliminates a potential useless read + write
cycle each time the baud rate is reconfigured.
