V4L/DVB (12748): em28xx: implement g_std v4l call
We need to implement the g_std call, or else the default norm always gets
returned, which breaks VBI capturing if you had changed the standard to NTSC
using s_std.
I had temporarily changed the default norm to NTSC so that zvbi-ntsc-cc
wouldn't choke, so now that we are returning the correct value, switch it back
to PAL as the default.
This work was sponsored by EyeMagnet Limited.
