I removed all "analog" drivers from the main CVS repository and moved them
to a separate "analog-2.4" directory. Main reasons:

- the drivers don't have anything to do with dvb 8-)

- the drivers are already in the kernel (besides the "Hexium" driver)
  and don't change that much any more

- the analog drivers rely on the i2c subsystem, which was heavily modified
  between 2.4 and 2.5. When making a new DVB patchset I have to work around
  these differences every time, which is very annoying

/* the tea6415c's design is quite brain-dead. although there are
   8 inputs and 6 outputs, these aren't enumerated in any way. because
   I don't want to say "connect input pin 20 to output pin 17", I define
   a "virtual" pin-order. */
