wireless: add new wil6210 802.11ad 60GHz driver 

This adds support for the 60 GHz 802.11ad Wilocity card
through a new driver, wil6210. Wilocity implemented the
firmware, QCA maintains the device driver.

Currently supported:

- STA: with security
- AP: limited to 1 connected STA, security disabled
- Monitor: due to a hardware/firmware limitation
  either control or non-control frames are monitored

Using a STA and AP with this drive, one can assemble
a fully functional BSS. Throughput of 1.2Gbps is achieved
with iperf.

The wil6210 cards have on-board flash memory for the
firmware, the cards comes pre-flashed and no firmware
download is required.

For more details see:

config WIL6210

depends on CFG80211
depends on PCI
default n
---help---
This module adds support for wireless adapter based on
wil6210 chip by Wilocity. It supports operation on the
60 GHz band, covered by the IEEE802.11ad standard.
http://wireless.kernel.org/en/users/Drivers/wil6210
If you choose to build it as a module, it will be called
wil6210
config WIL6210_ISR_COR
bool "Use Clear-On-Read mode for ISR registers for wil6210"
depends on WIL6210
default y
---help---
ISR registers on wil6210 chip may operate in either
COR (Clear-On-Read) or W1C (Write-1-to-Clear) mode.
For production code, use COR (say y); is default since
it saves extra target transaction;
For ISR debug, use W1C (say n); is allows to monitor ISR
registers with debugfs. If COR were used, ISR would
self-clear when accessed for debug purposes, it makes
such monitoring impossible.
Say y unless you debug interrupts
