Pantelis Koukousoulas 25d8527a44 V4L/DVB (5035): Pvrusb2: Enable radio mode round #2 
This is the logic that:
  a) Ensures /sys/class/pvrusb2/sn-*/ctl_frequency/{max,min}_val are
     "automagically" reset to sane values on each mode change.

  b) Allows tuning to a radio frequency by something like:
     echo `perl -e "print int(94.9*16000 + 0.5)"` \
       > /sys/class/pvrusb2/sn-*/ctl_input/cur_val


The trick was to take advantage of the already existing .get_{min,max}_value
function pointers in pvr2_ctrl, to "dynamically override" the hardcoded values
for min/max frequency at runtime.

For a moment I thought to dispose of the hardcoded MIN/MAX_FREQ and use the
hirange/lowrange fields of the v4l2_tuner struct instead, but then I see that
tuner-core.c kinda hardcodes these as well, so I decided to not bother.
