Subject: [PATCH v3 4/4] media: chips-media: wave5: Support YUV422 raw pixel-formats on the encoder.

From: "Jackson.lee" <jackson.lee@...psnmedia.com>

Add support for the YUV422P, NV16, NV61, YUV422M, NV16M, NV61M raw pixel-formats to the Wave5 encoder.
All these formats have a chroma subsampling ratio of 4:2:2 and therefore require a new image size calculation as the driver previously only handled a ratio of 4:2:0.
