With the driver for nxp,lpc3220-dmamux we can remove the pl08x platform
data and let pl08x driver to create peripheral channels from the DT
properties.

Feel free to ignore all comments from Markus, regardless whether the
suggestion is reasonable or not. This person is banned from LKML and
several maintainers ignore Markus' feedback, because it is just a waste
of time.
