For STA mode, collect VHT realated IEs from the Beacons or Probe
Responses and append similar VHT related IEs to association
requests.
For AP mode, get VHT related capability information and share it
with cfg80211 at the time of wiphy register. This information is
further used by cfg80211 and hostapd to start an AP with 802.11AC
support.
Currently only 8897 supports 802.11AC.

It's observed that reconfiguration of tx buffer size before
association can cause data path failure in firmware after
associated. Although this is only found with PCIe cards, but
potentially it could happen with any other interfaces as well.
The tx buffer reconfiguration is not really useful in firmware.
Let's remove it for all interfaces.

HostCmd_CMD_AMSDU_AGGR_CTRL is never called with GET action.
So the code in mwifiex_ret_amsdu_aggr_ctrl() becomes redundant.

This patch adds support for handling BA request and BA setup
events for AP interface.
RA list is marked as either 11n enabled or disabled from station's
capabilities in association request. BA setup is initiated only
after some specific number of packets for particular RA list are
transmitted.

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.
For example, this cast:
int y;
int *p = (int *)&y;
I used the coccinelle script below to find and remove these
unnecessary casts. I manually removed the conversions this
script produces of casts with __force, __iomem and __user.
@@
type T;
T *p;
@@
- (T *)p
+ p
Neatened the mwifiex_deauthenticate_infra function which
was doing odd things with array pointers and not using
is_zero_ether_addr.

In some cases local pointers are used to cast void pointers passed to
the function. Those unnecessary local pointers are also removed.
This patch was inspired by Joe Perches' patch
[PATCH net-next 1/2] wireless: Remove casts of void *;
and the comments from Julian Calaby.

1) Initialise HT capabilities in cfg80211 properly.
2) Cfg80211 stack may modify "sband->ht_cap" to disable
40Mhz operation in 2.4GHz band (after recent patch
"cfg80211: module_param to disable HT40 in 2.4GHz band")
Therefore read "sband->ht_cap" instead of an adapter variable
"hw_dot_11n_dev_cap" to get HT capabilities.
