V4L/DVB (5570): V4l1-compat: misc fixes for pixelformat function 

Mark the palette2pixelformat lookup table as const

pixelformat is unsigned, adjust the palette2pixelformat table and
pixelformat_to_palette()

palette_to_pixelformat() is a pure function

pixelformat_to_palette() is a const function
