The msm_serial_hs driver uses mach specific dma APIs. This is not
compatible with the multi-platform ARM effort. Let's only compile
this driver on MSM devices that are prepared to support it;
allowing the DT based MSM devices to enter the multi-platform ARM
build.

Do you have a plan to deal with this in the future? Aren't you going
to need it in the future on modern SoCs?

Yes, we plan to add the code for dma based serial devices into the
msm_serial.c driver. In the process we'll use the linux DMA apis instead
of using mach specific ones.
