iio: events: Make iio_push_event() IRQ context save
Currently it is not save to call iio_push_event() from hard IRQ context since
the IIO event code uses spin_lock()/spin_unlock() and it is not save to mix
calls to spin_lock()/spin_unlock() from different contexts on the same lock.
E.g. if the lock is being held in iio_event_chrdev_read() and an interrupts
kicks in and the interrupt handler calls iio_push_event() we end uo with a
deadlock.
This patch updates iio_push_event() to use spin_lock_irqsave()/
spin_unlock_irqstrestore(), since it can be called from both IRQ and non-IRQ
context. All other other users of the lock, which are always run in non-IRQ
context, are updated to spin_lock_irq()/spin_unlock_irq().

`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.

device before calling `comedi_pci_disable()`.

staging: comedi: adv_pci_dio: restore PCI-1753E support
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.
