[SERIAL] amba-pl010: allow platforms to specify modem control method
The amba-pl010 hardware does not provide RTS and DTR control lines; it is expected that these will be implemented using GPIO. Allow platforms to supply a function to implement manipulation of modem control lines. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
