by user-side, e.g. for use as a terminal, then there are race conditions
which can lead to terminal input being disabled and console output being
corrupted. This small patch series fixes these.

serial: amba-pl011: use port lock to guard control register access
serial: amba-pl011: factor out code for writing LCR_H register
serial: amba-pl011: preseserve hardware settings during initialisation
