Now that the usb (*probe) is handled in the comedi_driver (*auto_attach)
the comedi_driver (*detach) will be called automatically if the
attach fails.

The tidy_up() calls in the (*auto_attach) are not needed. Remove them
and absorb the code in tidy_up() into the (*detach).

Now that the private data is kzalloc'ed when the device is attached,
the NUMUSBDUXFAST define is not used. Remove it.

The SUBDEV_AD define is only used when setting up the subdevice.
Remove it and just open-code the value.

Currently, the usb_driver (*probe) locates a free place in the static
usbduxfast array to use for the private data in this driver. It then
does some initial setup of the usb device and allocates the buffers
needed. The firmware for the device is then requested and uploaded
before calling comedi_usb_auto_config() to allow the comedi core to
complete the (*auto_attach) of the device.

Move the bulk of the (*probe) into the comedi_driver (*auto_attach).
This allows the private data to be kzalloc'ed. We can then remove the
static array along with the semaphore that protected it.

This also removes the 16 attached devices limitation.

The usb_driver (*disconnect) calls comedi_usb_auto_unconfig() then
frees any allocations by calling tidy_up(). comedi_usb_auto_unconfig()
calls the comedi_driver (*detach) function, usbduxfast_detach().

Move the tidy_up() call into usbduxfast_detach() and use the
comedi_usb_auto_unconfig() directly for the (*disconnect).

Rename the CamelCase function,

Rename some of the local variables to the normal names used in
comedi drivers. Add a local variable for the comedi_async *.

Remove the sanity checking. The urb that causes this function to
be called can only be submitted if the sanity checks already
passed.

Change the way the comedi_subdevice is fetched. The attach function
sets the dev->read_subev pointer to the correct subdevice. Use that
instead of accessing the dev->subdevices array directly.

Type of 'probe_rsp->rawData[1]' is 'hcf_8' which is 'u8', it will
compare with 'int', so use min_t() to cast to 'u8' to avoid related
warning.

If use min(), it has '(void) (&_min1 == &_min2);', so if no type cast,
the compiler will report 'pointer types lacks a cast':

The bits needed to set the analog input gain can be simply calculated
based on the 'range'.

The LabPC versions of the board do not have the '0x10' gain that the
LabPC+ board supports. By incrementing the range appropriately the
correct gain bits can still be calculated.

This allows removing the two gain tables, as well as the export, along
with the 'ai_range_code' data in the boardinfo.
