ARM: PL08x: avoid duplicating registers in txd and phychan structures

As we now have all the code accessing the phychan {csrc,cdst,clli,cctl,
ccfg} members in one function, there's no point storing the data into
the struct.  Get rid of the struct members.  Re-order the register dump
in the dev_dbg() to reflect the order we write the registers to the DMA
device.

The txd {csrc,cdst,clli,cctl} values are duplicates of the lli[0]
values, so there's no point duplicating these either.  Program the DMAC
registers directly from the lli[0] values.
