ath5k: fix spontaneus AR5312 freezes
Sometimes while CPU have some load and ath5k doing the wireless
interface reset the whole WiSoC completely freezes. Set of tests shows
that using atomic delay function while we wait interface reset helps to
avoid such freezes.
The easiest way to reproduce this issue: create a station interface,
start continous scan with wpa_supplicant and load CPU by something. Or
just create multiple station interfaces and put them all in continous
scan.
This patch partially reverts the commit
1846ac3dbec0 ("ath5k: Use
usleep_range where possible"), which replaces initial udelay()
by usleep_range().
I do not know actual source of this issue, but all looks like that HW
freeze is caused by transaction on internal SoC bus, while wireless
block is in reset state.
Also I should note that I do not know how many chips are affected, but I
did not see this issue with chips, other than AR5312.

Ath10k driver sets wrong default key idx that results in
sending unicast frames with multicast key.
The reason for this behavior is that cached broadcast key
is installed for station MAC address on association. After
dot1x completes, unicast key is installed for station
MAC address. Default key idx is set to broadcast key id when
driver tries to send broadcast frame. This causes firmware
to use broadcast key id to transmit unicast frames to stations.

ath10k: implement per-vdev wmm param setup command
New wmi-tlv firmware for qca6174 supports this.
This will be used soon.

ath10k: move wmm param storage to vif
mac80211 already requests WMM per vif but firmware
wasn't able to handle this until now. However new
wmi-tlv firmware for qca6174 is capable of this.
This prepares per-vif WMM param setup.

b43: AC-PHY: prepare place for developing new PHY support
There are new (not anymore?) Broadcom 802.11ac wireless cards based on
chipsets like BCM4352 and BCM4360. They use a new PHY type (called
simply AC) that will require new specific code.

bcma: implement host code support for PCIe Gen 2 devices
This is stil incomplete, so we don't add PCI IDs of new devices yet.
Purpose of this patch is to allow testing & adjusting rest of the code.
