Both 10 and 12-bit Bayer formats are stored aligned as 16-bit values
in memory, not unaligned 10 or 12 bits.
Since the current code for retreiving the bpp is used only to
calculate the memory storage size of the picture (which is what
pixel formats describe, unlike media bus formats), fix it there.
