We used single shared fbops struct and patched it at fb init time with

it was either sending NV50-style commands to all cards, or NV04-style

The general idea is to validate the current hw state
against the set of power states and select a power
state based on that. This patch just pulls the power
states from the bios and prints the information. It
is not currently hooked up in the actual power management
code. Hooking it up will require reworking the the current
power state selection code and will be handled in a future
patch.
Additionally, we'd need to decide on some default lower
power states for cards without power tables.

v3 - fix typo in pm init on pre-atom cards, handle pre-atom
cards without x86 bioses

Reinette found the reason for the warnings that
happened occasionally when a hw-offloaded scan
finished; her description of the problem:
mac80211 will defer the handling of scan requests if it is
busy with management work at the time. The scan requests
are deferred and run after the work has completed. When
this occurs there are currently two problems.
* The scan request for hardware scan is not fully populated
with the band and channels to scan not initialized.
* When the scan is queued the state is not correctly updated
to reflect that a scan is in progress. The problem here is
that when the driver completes the scan and calls
ieee80211_scan_completed() a warning will be triggered
since mac80211 was not aware that a scan was in progress.
The reason is that the queued scan work will start
the hw scan right away when the hw_scan_req struct
has already been allocated. However, in the first
pass it will not have been filled, which happens
at the same time as setting the bits. To fix this,
simply move the allocation after the pending work
test as well, so that the first iteration of the
scan work will call __ieee80211_start_scan() even
in the hardware scan case.
