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.

I'm not sure I got it right. Is the values from DT now clampet as well
as user space does or other way around? In either way the commit
message misses the explanation why it's not a problem if user
previously passed bigger values either via user space or via DT,
because it's an ABI change, right?

Values are now clamped to 100 ms if set by userspace via ioctl and
not clamped at all if set by DT. I will improve the commit message
to make this more clear.

Thanks,
Lino
