iwlwifi: mvm: abort scheduled scan upon RFKILL
When we have an active scheduled scan, and the RFKILL
interrupt kicks in, the stack will cancel the scheduled
scan as part of the down flow. But cancelling scheduled
scan usually implies sending a command to the firwmare
which has been killed as part of the RFKILL interrupt
handling.
Because of that, we returned an error to mac80211 when
it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.
To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.

wil6210: workaround for BACK establishment race
When establishing BACK, WMI may be handled earlier then Rx, in this case
late Rx will be mis-handled.
Detect early Rx and pass it to the stack, bypass reordering

Rx high threshold interrupt is reported by the hardware in case

wil6210: add advanced interrupt moderation
Add advanced interrupt moderation support available since "Sparrow B0".
Legacy interrupt moderation used only one counter to moderate tx, rx,
and misc interrupts.
Advanced interrupt moderation bypasses misc, and handles separately tx
and rx interrupts. In addition it has two timers for each interrupt type.
Max burst duration timer which defines how long to postpone interrupt after
first event (receive event for rx and tx complete event for tx), and
interframe timeout which defines how to determine the end of the burst and
issue interrupt even if the first timer still pending.
Capabilities flags in wil_priv is set on initialization according to
HW. The rest of the code checks for advanced interrupt capability bit
in capabilities flags field.
Debugfs is split accordingly: "legacy" interrupt moderation remains
unchanged, new debugs files added for advanced interrupt moderation
support.
Module params are aligned to support advanced interrupt moderation
(tx & rx). When not available (for legacy interrupt moderation) will
use only rx configuration; Tx configuration will be ignored in this
case.
