libcamera: Use V4L2PixelFormat::fromPixelFormat()

Browse source 
Replace manual searches for V4L2 pixel format in the PixelFormatInfo
with the V4L2PixelFormat::fromPixelFormat() helper function. This
prepares for multi-planar support that will modify how V4L2 pixel
formats are stored in PixelFormatInfo.
