[PATCH v2 4/9] serial: core: sanitize RS485 delays read from device tree

[Lino Sanfilippo]

From: Lino Sanfilippo <l.sanfilippo@xxxxxxxxxx>

When setting the RS485 configuration from userspace via TIOCSRS485 the
delays are clamped to 100ms. Make this consistent with the values passed
in by means of device tree parameters.
