libcamera: formats: Reimplement V4L2 PixelFormatInfo::info()

Browse source 
The PixelFormatInfo::info(const V4L2PixelFormat &format) function
returns the PixelFormatInfo associated with a V4L2 pixel format.

As the pixelFormatInfo map is indexed using PixelFormat and a V4L2
format can easily be converted to a PixelFormat, simply return
the info() function overload instead of maintaining two similar
implementations of the same function.
