If multiple scan plans were set for scheduled scan, do not restart
scheduled scan on reconfig because it is possible that some scan
plans were already completed and there is no need to run them all
over again. Instead, notify userspace that scheduled scan stopped
so it can configure new scan plans for scheduled scan.

Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.
When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.

For location and connectivity services, userspace would often like
to know the time when the BSS was last seen. The current "last seen"
value is calculated in a way that makes it less useful, especially
if the system suspended in the meantime.
Add the ability for the driver to report a real CLOCK_BOOTTIME stamp
that can then be reported to userspace (if present).
Drivers wishing to use this must be converted to the new API to call
cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They
need to ensure the reported value is accurate enough even when the
frame might have been buffered in the device (e.g. firmware.)

The icp_multi_reset() function currnelt does the following during the
(*auto_attach) and (*detach) of this driver:
1) disables all interrupts and clears any pending requests
2) resets the analog output channels to 0V (0..5V range)
3) sets all digital output channels to 0
Interrupts are not used by this driver so the disable/clear when
detaching is not necessary.
Depending on the use, reseting the analog and digital outputs when the
driver is detached might not be desireable.
Remove the board reset during the (*detach) and use comedi_pci_detach()
directly.
