Unified base offset and Y plane offset into a single variable,
moved all ipu_cpmem_set_buffer calls to a single location.
Removed NV21 and NV61 for now. The IDMAC doesn't understand U/V
order for chroma interleaved formats, so we'd need to work around
this by implenting U/V switching via the CSC unit.

Add a second buffer physaddr to struct ipu_image, for double-buffering

Move channel parameter memory setup functions and macros into a new
submodule ipu-cpmem. In the process, cleanup arguments to the functions
to take a channel pointer instead of a pointer into cpmem for that
channel. That allows the structure of the parameter memory to be
private to ipu-cpmem.c.
