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.

function (s626_debi_transfer()) which is called from critical sections,
so comedi_timeout() is unusable for them, and an iterative timeout is
used instead. For the while loops in a context where comedi_timeout() is
allowed, a new callback function, s626_send_dac_eoc(), has been defined
to evaluate the conditions that the while loops are testing. The new
callback employs a switch statement based on a simple new enum so that
it is usable for all of the different conditions tested in while loops
in s626_send_dac(). The proper comedi_timeout() calls are then used.
