Unfortunately, advertising P2P_DEVICE support was a little
premature, a number of issues came up in testing and have
been fixed for 3.10. Rather than try to backport all the
different fixes, disable P2P_DEVICE support in the drivers
using it. For iwlmvm that implies disabling P2P completely
as it can't support P2P operation w/o P2P Device.

Recently in low power (LP) mode FW moved from active to power save mode
after TX/RX completion faster than in balanced power mode (BPS).
Change AM-to-PSM transition time so that it will be the same as for BPS.

first_antenna is supposed to return the first antenna as a
0-based bitmap: ANT_A is BIT(0), ANT_B is BIT(1), etc...
Since ffs is 1 based (ffs(BIT(0)) = 1), then we had an
off-by-one bug:
BIT(ffs(ANT_A)) = BIT(ffs(BIT(0))) = BIT(1) = ANT_B.
So what we really want is:
BIT(ffs(ANT_A) - 1) = BIT(ffs(BIT(0)) - 1) = BIT(0) = ANT_A.

Using IWL_MVM_STATION_COUNT and IWL_INVALID_STATION together
isn't a good idea as they have different values. Always use
IWL_MVM_STATION_COUNT for an invalid station in MVM and move
the definition of the IWL_INVALID_STATION constant into the
DVM driver to avoid making such mistakes again. The one use
in the transport code can be hard-coded to -1 instead as the
station ID is passed as an integer there.

Many platforms have issues processing a wakeup signal
while they're still suspending, and will ignore it.
Since our device thinks it woke the platform, and the
platform ignored the signal, it will sleep without
WoWLAN being enabled as the device disables WoWLAN
when having woken the platform.
Resolve this by making the device wait for 10 seconds
after getting the suspend signal before waking up the
platform.

Currently power management is supported only when only a single
virtual interface is present. The driver verifies number of created
interfaces and disables power management when multiple interfaces
present. However, this rule does not extend to a P2P device that is
handled differently in the firmware. If a P2P device is added power
management can remain enabled.
