This isn't related to whether or not "fw can be loaded",
but rather requesting that ME go into a state where doing
a product reset is safe. This is related to FW load only
in the specific case of where it's used today in iwlmvm,
notably when it's known that the firmware itself will (or
at least may) do a product reset during load.
Clarify the documentation.
I was tempted to rename things too, but on the ME side it
really is also called PLDR (which is a Windows term and
may not even match the complete behaviour since doing a
full product reset from the driver also requires calling
an ACPI method first.) So keep the name aligned with ME.

PLDR (product level device reset) is a Windows term, and
is something the driver triggers there, AFAICT.
Really what 'pldr_sync' here wants to capture is whether
or not the firmware will/may do a product reset during
initialization, which makes the device drop off the bus,
requiring a rescan. If this is the case, obviously the
init will fail/time out, so we don't want to report all
kinds of errors etc., hence this tracking variable.
Rename it to 'fw_product_reset' to capture the meaning
better.

AP interfaces fundamentally cannot leave the channel, so multi-
channel operation with them isn't really possible. We shouldn't
advertise support for such, at least not as long as we don't
have full multi-radio support. Thus, remove the AP bit from the
interface combinations for two channels and add another set for
just one channel that has it.
Also, to avoid duplicating everything even more, unify the NAN
and non-NAN cases.

Public action extended channel switch announcement (ECSA)
frames cannot be protected well, the spec is unclear about
what should happen in the presence of stations that can
receive protected dual and stations that cannot.
Mitigate these issues by not treating public action frames
as the absolute truth, only treat them as a hint to stop
transmitting (quiet mode), and do the remainder of the CSA
handling only when receiving the next beacon (or protected
action frame) that contains the CSA; or, if it doesn't,
simply stop being quiet and continue operating normally.
This limits the exposure to malicious ECSA public action
frames, since they cannot cause a disconnect now, only a
short interruption in traffic.
