V4L/DVB (8092): videodev: simplify and fix standard enumeration
VIDIOC_ENUMSTD did not return all the PAL/SECAM/NTSC variants: it just returned one single PAL/SECAM/NTSC standard without separate entries for the trickier standards like NTSC-JP. Changed the code so that it behaves better. Also simplified the if/switch statements into a common standards lookup table.
