ARM: PL08x: assign ccfg DMA request signal in prep_phy_channel()

Browse source

There is no need to wait until we start processing a tx descriptor
before setting up the DMA request selection in the ccfg register.
We know which channel and request will be used in prep_phy_channel(),
so setup the ccfg request selection at txd creation time in
prep_phy_channel().
