ath10k: enable wmi ps peer param command for 10.x FW

Enable ap_ps_peer_param_cmdid for 10.x FW.
This is used mainly for AP UAPSD.

ath10k: enable firmware STA quick kickout

Firmware has a feature to track if the associated STA is not acking the frames.
When that happens, the firmware sends WMI_PEER_STA_KICKOUT_EVENTID event to the
host. Enable that to faster detect when a STA has left BSS without sending a
deauth frame.

Also set huge keepalive timeouts to avoid using the keepalive functionality in
the firmware.

ath10k: AP mode, set UAPSD params correctly

ath10k handles UAPSD completly in the firmware.
When works in AP mode we have to configure
UAPSD params for each station. Without this
patch we configure UAPSD params before we
send peer assoc command to the FW, which was
wrong. Next FW didn't know what should be trigger
frame, couse UAPSD didn't work correctly in AP mode.
To configure UAPSD params correctly we have to
send them after peer assoc command.

ath10k: fix the printing of 10.x FW version when FW crashed

10.x FW has no structure member sw_version_1. Thus,
both fw_version_release and fw_version_build are not
available. The provided fw_version_major is also wrong.
Fix this by using the fw_version from struct wiphy.

ath10k: implement channel switching

Until now channel change wasn't propagating to FW
directly because operational channel is abstracted
by VDEVs and it wasn't really necessary since
ath10k implements hwscan and hwroc.

This effectively fixes STA CSA and allows for
future AP-like CSA as well.

ath10k: implement AP CSA

Most channel switching logic has been implemented
already so this patch is pretty small. The patch
makes use of mac80211's vif->csa_active for AP CSA
handling.

ath10k: implement and use new beacon method

Until now ath10k used a copy-by-value beacon
submission.

The new method passes a DMA address via WMI
command only. This command contains additional
metadata that fixes AP behaviour with regard
to powersave buffering.

This also fixes strange bug when multicast traffic
would freeze TX indefinitely.

ath10k: properly return err from start()

If recovery failed ath10k returned 0 (success) and
mac80211 continued to call other driver callbacks.
This caused null dereference.

This is how the failure looked like:

ath10k: failed to connect to HTC: -110
ath10k: could not init core (-110)

ath10k: configure access category for arp

ARP frames exchange does not work properly for UAPSD enabled AP.
ARP requests which arrives with access category 0 are processed
by network stack and send back with access category 0. FW changes
access category to 6. This is causing problems when UAPSD associated
STA is sleeping after has sent ARP request. Configure ARP access
category in FW to best effort (0) solves this problem. ARP frames
will be send with access category 0.

Simplify arp ac override functionality by removing redundant entry in
pdev param maping table. There should be only one entry in pdev param
map but enum has different name for different FW.
