Sujith Manoharan d67ee53393 ath9k_htc: Introduce new HTC API
A new routine that takes an endpoint explicitly is
introduced. The normal htc_send() now retrieves the endpoint
from the packet's private data. This would be useful
in TX completion when the endpoint ID would be required.
While at it, use a helper function to map the queue to endpoint.

Data/mgmt/beacon packets use htc_send(), while WMI comamnds
pass the endpoint to HTC.

Sujith Manoharan 40dc9e4b86 ath9k_htc: Use SKB's private area for TX parameters
For all packets sent through the USB_WLAN_TX_PIPE endpoint,
the private area of the SKB's tx_info can be used to store
driver-specific information. For packets sent through USB_REG_OUT_PIPE,
this will not make a difference since they are routed through a
separate routine that doesn't access the private region.

This would help in situations where TX information is required
in the URB callback.

Rajkumar Manoharan fa6e15e0b5 ath9k_htc: Identify devices using driver_info
Categorize AR7010 & AR9287 devices based on driver_info
of usb_device_id, instead of PIDs. This avoids per-device cases
and minimize code changes for new device addition.

Sujith.Manoharan@atheros.com 8116daf214 ath9k_htc: Fix array overflow
Use ENDPOINT_MAX instead of HST_ENDPOINT_MAX.
This fixes a stack corruption issue.

This is based on a patch sent by Dan Carpenter <error27@gmail.com>.

Sujith.Manoharan@atheros.com d8c49ffb2e ath9k_htc: Fix target ready race condition
The ready message from the target could be processed
before the host HW init has completed. In this case,
htc_process_target_rdy() would assume the target has timed
out, when it hasn't. Fix this by checking if the target
has sent the ready message properly.

Sujith.Manoharan@atheros.com 47fce026d5 ath9k_htc: Reorder HTC initialization
The HTC state has to be setup before initializing
the target because the ready message could possibly
come before the control endpoints in HTC have been
identified.

Sujith 7f1f5a0060 ath9k_htc: Fix sparse endian warnings
This patch fixes a bunch of endian issues that
were exposed by sparse. It's a miracle that the driver
worked at all till now.

The Lord be praised.
