`labpc_common_detach()` calls `comedi_pci_disable()` unconditionally.
That's okay for PCI devices and harmless for ISA devices (as the
`hw_dev` member will be NULL so `comedi_to_pci_dev()` will return NULL
and `comedi_pci_disable()` checks for that), but it is disastrous for
PCMCIA devices. Those are managed by the "ni_labpc_cs" module but it
calls this `labpc_common_detach()` and the `hw_dev` member will be
pointing to the `struct device` embedded in a `struct pcmcia_device` in
that case. That's enough to confuse `comedi_pci_disable()` into
thinking it's a valid PCI device to be disabled.
Use the private board information (`thisboard`) to make sure it is a PCI
device before calling `comedi_pci_disable()`.

Some PCI drivers use the "spare" `iobase` member of `struct
comedi_device` as a flag to indicate that the call to
`comedi_pci_enable()` was successful. This is no longer necessary now
that `comedi_pci_enable()` and `comedi_pci_disable()` use the
`ioenabled` member of `struct comedi_device` themselves to keep track of
what needs to be done.
Remove the unnecessary assignments to the `iobase` member in the
relevant drivers.

Add 1-bit bit-field member `ioenabled` of type `bool` to `struct
comedi_device`. Use this to keep track of whether a PCI device and its
BARs have been successfully enabled by `comedi_pci_enable()`. This
avoids overloading the meaning of the `iobase` member which is used by
several drivers to hold the base port I/O address of a board's "main"
registers. Other drivers using MMIO use `iobase` as a flag to indicate
that the preceding call to `comedi_pci_enable()` was successful. They
no longer need to do that.
The name `ioenabled` is intended to be PCI-agnostic so it can be used
for similar purposes by non-PCI drivers.

Florent Boudet reports success using a NI PXI-6624 board with a
trivially modified version of the "ni_660x" driver (addition to the PCI
device ID table and comedi board table). He did this with the
out-of-tree Comedi drivers at www.comedi.org, but it applies equally to
the in-tree "staging" drivers.
He reports the PXI-6624 is basically the same as the PXI-6602, but with
isolated channels and external voltage source.
Add support for NI PXI-6224 to the "ni_660x" driver.
(Maybe the driver should be renamed to "ni_66xx"?)

Back in the old days (before "staging") when Comedi only supported
manual configuration of devices, the "adv_pci_dio" driver supported both
PCI-1753 ("pci1753") and PCI-1753E ("pci1753e"). In actual fact,
"pci1753e" is just a PCI-1753 connected by a ribbon cable to a PCI-1753E
expansion card, which is plugged into a PCI slot but is not a PCI device
itself. Now that the "adv_pci_dio" driver only supports automatic
configuration of devices and the main "comedi" module no longer allows
auto-configuration to be disabled, a PCI-1753 with a PCI-1753E expansion
card is always treated as an unexpanded PCI-1753 ("pci1753") and there
is no way to override it. (Recently, an undefined macro
`USE_PCI1753E_BOARDINFO` was used to make the driver switch to
supporting "pci1753e" instead of "pci1753", but this is less than
ideal.)
Advantech has their own Linux (non-Comedi) driver for the PCI-1753 which
detects whether the PCI-1753E expansion card is connected to the
PCI-1753 by fiddling with a register at offset 53 from the main
registers base.
Use Advantech's test in our "adv_pci_dio" driver. If the board appears
to be a PCI-1753 ("pci1753"), check if the expansion card appears to be
present, and if so, treat the device as a PCI-1753 plus PCI-1753E
expansion card ("pci1753e").
Also, get rid of `enum dio_boardid` (`BOARD_...` enum values) which was
added recently and just use the older `TYPE_...` enum values from `enum
hw_cards_id` instead as the mapping is now 1-to-1.

Because there is a need to lock inside IRQ handler, this patch
changes the locking mechanism inside the omap-bandgap.[c,h] to
spinlocks. Now this lock is used to protect omap_bandgap struct
during APIs exposed (possibly used in sysfs handling functions)
and inside the ALERT IRQ handler.
Because there are registers shared among the sensors, this lock
is global, not per sensor.

Now arch code has to specify CONFIG_ARCH_HAS_BANDGAP. So, this driver
will be selectable only if the platform reports itself as having a
bandgap device.
Any OMAP variant or any other OMAP version needs to
select ARCH_HAS_BANDGAP
so that the driver will be applicable. A part from that it is
required to device the data structures that maps the registers
and their bitfields. The DT compatible list must also be updated.
