staging: comedi: amplc_dio200: remove dio200_common_detach()
This exported function just does a free_irq() to release the interrupt
handler for the legacy and PCI dio200 drivers.
The legacy driver also calls comedi_legacy_detach() which would also
do the free_irq(). For that driver the just use comedi_legacy_detach()
directly for the (*detach).
For the PCI driver, add the free_irq() to the private (*datach) function.
Remove the, then unused, dio200_common_detach() function.

This member of the boardinfo is only set for the PCIE boards. Use the

staging: comedi: amplc_dio200.h: rename 'has_enhancements' in boardinfo
This member of the boardinfor is only set for the PCIE boards. For
aeshetics, rename it to 'is_pcie'.
For clarity, use this flag in the (*auto_attach) to determine if the
dio200_pcie_board_setup() function needs to be called instead of using
the switch (context_model).

staging: comedi: amplc_dio200.h: remove struct dio200_layout definition
This struct is used to provide part of the boardinfo data. Using the extra
indirection does not provide any additional clarity to the driver.
Absorb the members from dio200_layout into dio200_board and remove the
extra 'layout' indirection.
For aesthetics, rename all the local variables used for the boardinfo
pointer to 'board'.

staging: comedi: amplc_dio200: remove private data
The private data in this driver only has one member, 'intr_sd', which is
the index to the interrupt subdevice.
This member is initialized during the attach of the driver when the sd_intr
subdevice is detected in the boadinfo 'layout'. The member is then used in
the interrupt handler to get the pointer to the subdevice.
This member is not necessary. The comedi_device 'read_subdev' is also
initialized during the attach. This can be used in the interrupt handler
to get the subdevice pointer.
Refactor the code to not require the private data and remove the struct
and its allocations.

staging: comedi: remove FSF address from boilerplate text
Addresses change...
Remove the paragraph with the FSF address from all the comedi source
files.
Also, remove the paragraph about the finding the complete GPL in the
COPYING file since it's unnecessary.

staging: comedi: amplc_dio200: split into ISA, PCI and common
Split the "amplc_dio200" comedi driver module into separate driver
modules for ISA and PCI boards with a common module for the shared code.
Keep the old name "amplc_dio200" for the ISA board driver as the module
may be modprobed with this name by a script. (If the script uses insmod
it will need modifying to load the "amplc_dio200_common" module first.)
Use the module name "amplc_dio200_pci" for the PCI board driver. On
most systems this will be auto-loaded.
Use the module name "amplc_dio200_common" for the module containing the
shared code. This is normally loaded as a dependency of the other two
modules.
"amplc_dio200_common" exports the following functions:
* `amplc_dio200_common_attach()`: this is basically the old
`dio200_common_attach()` from the combined driver module. It is
called from the driver-specific attach or auto-attach routines.
* `amplc_dio200_common_detach()`: this is most of the old
`dio200_detach()`. It is called from the driver-specific detach
routine.
* `amplc_dio200_set_enhance()`: this is a new function called during
initialization of PCIe cards to enable "enhanced" mode.
