[PATCH v1 3/4] media: chips-media: wave5: Support CBP profile

[Jackson.lee]

From: Jackson Lee <jackson.lee@xxxxxxxxxxxxxxx>

Constrained Baseline Profile (CBP) and Baseline Profile (BP) have been
treated as the same.
Introduce the ability to differentiate between the two.

Fixes: 9707a6254a8a ("media: chips-media: wave5: Add the v4l2 layer")
