staging: comedi: adv_pci1710: don't "reset" board when detaching

Currently this driver calls pci1710_reset() during the (*detach) of
the driver. That function does the following:

  1) program the control register to stop any operations
  2) clears the analog input FIFO
  3) clears any pending interrupts
  4) sets all the analog output channels to unipolar 5V range and 0V output
  5) sets all the digital outputs to 0V

Before detaching the comedi core will (*cancel) any running async commands.
This will handle 1-3 above.

Depending on the application, it might not be safe to reset the analog and
digital outputs when the driver is detached.

Remove the board reset when detaching and just use comedi_pci_detach()
directly for the driver (*detach).

staging: comedi: adv_pci1710: remove 'has_counter' boardinfo

All the boards supported by this driver have a 8254 counter. Channels
1 and 2 are used to create the cascaded 32-bit analog input pacer.
Counter 0 is available for the user on all the boards except the PCI-1713.

Remove the 'has_counter' boardinfo and use the 'is_pci1713' boardinfo to
determine if the user counter subdevice needs to be allocated and
initialized.

staging: comedi: adv_pci_dio: separate out PCI-1760 support

The PCI-1760 is board unique. It uses an outgoing/incoming mailbox
programming sequence to access the hardware. The other boards supported
by this driver use simple register mapping. Including support for the
PCI-1760 in this driver just makes it harder to understand.

Separate out the PCI-1760 support into a new driver, adv_pci1760.

Clean up the new driver. The original code had a bunch of CamelCase and
other checkpatch.pl issues.

The code used to access the outgoing/incoming mailboxes was also a bit
awkward with the passing of the arrays for the outgoing and incoming
mailbox bytes. Replace them with two new functions that send a command
and return the feedback data from the command based on the programming
flow chart in the datasheet for the PCI-1760.

The new adv_pci1760 driver also fixes the incomplete timer subdevice.
This subdevice is actually the 2 PWM outputs so the subdevice type
has been changed to COMEDI_SUBD_PWM.

The counter subdevice support was not complete in the original code.
They are also a bit strange since they are up counters connected to
each of the digital inputs. For now that subdevice has been disabled
(COMEDI_SUBD_UNUSED).

staging/wilc1000: pass struct wilc to most linux_wlan.c functions

We want to get rid of all global variables in this driver, and
instead pass device structures from one function to another.
This changes the linux_wlan.c and wilc_wlan.c to do this
for the most part. There are a few exceptions where these
functions are themselves called from another part of the driver

staging/wilc1000: use more regular probing

So far, my patches tried to do equivalent conversions of the
existing code.  This one goes beyond that by restructuring
how the devices get probed. In particular, the spi driver
no longer creates the netdev until the device is probed,
and I've removed the global wilc_sdio_func and wilc_spi_dev
variables in favor of retrieving them from the wilc_dev
