3cc7772c0a mwl8k: factor out firmware loading and hw init code
This is in preparation for supporting different fw images for
different interface types, and for supporting asynchronous
firmware loading.

Based on a patch from Pradeep Nemavat <pnemavat@marvell.com>

ae63a33ec9 libertas: EHS_REMOVE_WAKEUP is not always supported
Certain firmware versions, particularly the 8388 found on the XO-1,
do not support the EHS_REMOVE_WAKEUP command that is used to disable
WOL. Sending this command to the card will return a failure that
would get propagated up the stack and cause suspend to fail.

Instead, fall back to an all-zero wakeup mask.

This fixes http://dev.laptop.org/ticket/9967

cf43298864 libertas: don't block usb8388 suspend if no wakeup conditions are set
This hunk added by commit 66fceb69b7 seems erroneous. We don't want to
prevent suspend of the whole system if no wakeup params are set.

In the case of the usb8388 we do want to keep the card powered up even
if there are no wakeup params. This is because it will continue acting
as a mesh node.

If the mesh is disabled, it would indeed make more sense to power down
the card during suspend, as the equivalent hunk does for the SD interface.
But that's a separate task; for now just restore the previous behaviour.

9236d838c9 cfg80211: fix extension channel checks to initiate communication
When operating in a mode that initiates communication and using
HT40 we should fail if we cannot use both primary and secondary
channels to initiate communication. Our current ht40 allowmap
only covers STA mode of operation, for beaconing modes we need
a check on the fly as the mode of operation is dynamic and
there other flags other than disable which we should read
to check if we can initiate communication.

Do not allow for initiating communication if our secondary HT40
channel has is either disabled, has a passive scan flag, a
no-ibss flag or is a radar channel. Userspace now has similar
checks but this is also needed in-kernel.

ae79d23d0b iwlagn: fix non-5000+ build
When building 4965 without 5000+ there were a
lot of build errors due to functions being used
that weren't even compiled in. To fix this move
some code around and only compile the HCMD code
for 5000+ series as it's not used for 4965.
