Use legacy NL80211 STA events for older drivers

This allows tethering on devices with older bcmdhd
drivers to be fixed.  It conditionally reverts
b638fe75d3cb9d21c67386173f10afe65053cc4d
"nl80211: Use native cfg80211 sta events" for these
boards.

Use BOARD_LEGACY_NL80211_STA_EVENTS to enable
this conditional revert.

Forward-port to JB MR1, squashed in Steve Kondik's commit
to handle additional changes.

wext: Re-add support for SIGNAL_POLL and DRIVER

Both of these are still used by JB, and wext wifi drivers have some
weird behaviors without it (like a reported poor connection 100% of
the time)

nl80211: add ifndef on AP SME condition

The condition causes problems on driver initialization if the
NL80211_ATTR_DEVICE_AP_SME is not available. Needs
BOARD_NO_APSME_ATTR:=true.

Fix regression in LEAP

Commit 458cb3019108b6cb8c0c1cab94ae6ebf244eda27 broke LEAP since it
rejects EAP-Success packet that is used within LEAP and this frame does
not have a payload. Fix LEAP by relaxing the generic EAP packet
validation if LEAP has been negotiated.
