gpu: ipu-v3: Add more planar formats support
Adds support for the following planar and partial-planar formats:
YUV422
NV12
NV16

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.
