This patch fixes following issues in p2p code paths.
1) bss role, bss type and connection type was not set correctly
for p2p GO and p2p client at couple of places.
2) Driver appends a proprietary header to management frames
which will be parsed by our firmware. Later while informing
TX status to cfg80211, modified frame buffer was passed to
cfg80211_mgmt_tx_status() instead of original one.

A long time ago, ath9k had issues during reset where the DMA engine
would stay active and could potentially corrupt memory.
To debug those issues, the driver would print warnings whenever they
occur.
Nowadays, these issues are gone and the primary cause of these messages
is if the MAC is stuck during reset or busy processing a long
transmission. This is fairly harmless, yet these messages continue to
worry users.
To reduce the number of bogus bug reports, turn these messages into
debug messages and count their occurence in the "reset" debugfs file.

FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.
A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range
The chirp detection has been tested with reference
radar generating devices and proved to work reliably.
