staging: comedi: das6402: rewrite broken driver

This driver is _really_ broken.

It initializes an analog input subdevice that only has a (*cancel)
function. It also does a request_irq() to hookup an interrupt handler
using it->options[0] as the IRQ. This option is actually the base
address of the I/O region used by the board. If the interrupt handler
actually did get hooked up, the rest of the code assumes that IRQ 10
is being used.

Rewrite the driver to properly support the hardware.

The DAS6402-12/16 boards have 64 single-ended / 32 differential analog
inputs, 2 analog outputs, 8 digital inputs, and 8 digital outputs. Add
proper support for these subdevices.

Stub in the analog input async command support.
