When a station entry is removed, there could still be
pending packets destined for that station in the HIF layer.
Sending these to the target is not necessary, so drain them
in the driver itself.

There is no point in looping over all the endpoints,
since the HIF layer uses the start/stop APIs only
for the TX pipe. Simplify the API accordingly.

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.

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.

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.

Use ENDPOINT_MAX instead of HST_ENDPOINT_MAX.
This fixes a stack corruption issue.

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.

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.

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.
