It is possible to configure the ucode to automatically send the probe
responses to the clients after they send a probe request. At least for
WPS the userspace needs to answer the probe requests and we do not know
a way to say to the ucode to just handle the normal probe requests, so
for now no probe requests should be handled by the ucode.

The ucode is able to answer probe response by itself. This writes such
a template into the specific memory. Currently the probe requests are
also send to mac80211 so there are more answers send to a requesting
client. We have to make the ucode stop sending probe requests to the
driver.

This makes it possible that a beacon template provided by mac80211 is
written to the hardware for constant beaconing.

This is based on an old version of brcmsmac, on b43 and the spec b43 is
based on.

FW can be woken up even by accessing device registers; we need
not explicitily enable interrupts for doing this. Future PCIe
devices will not be woken up by writing to host registers.
This patch enables driver to wake up device by reading FW status
register.

Also devices with sleep cookie enabled need some more time before
proceeding with processing. Handle this by adding a delay loop.

Spin locks and completions are expensive in hard IRQ context and cause
problems with RT kernels.  In RT kernels, both spin locks and
completions can schedule(), so we can't use them in hard irq context.
