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.

Starting with PL111, the 5551 or 565 modes can be configured in the

and sets the correct value.

Since the ARM AMBA bus is used on MIPS as well as ARM, we need
to make the bus available for other architectures to use. Move
the AMBA include files from include/asm-arm/hardware/ to
include/linux/amba/
