Originally the explicit fw register dump was added
to wait_for_target_init because interrupts are
masked early during power_up.
Due to some changes in power_up/reset sequences
sometimes when fw crashed ath10k would print the
dump more than once via hif_stop -> warm_reset ->
wait_for_target_init, possibly with different
values each.
Prevent this by doing the explicit fw register
dump only during power_up instead of
wait_for_target_init.

Thermal cooling device support is added to control the temperature
by throttling the data transmission for the given duration. Throttling
is done using hw MAC quiet time setting. Period, duration and offset
from TBTT can be set up to quiet the MAC transmits for the required duty
cycle (% of quiet duration). The thermal device allows user to configure
duty cycle.
The quiet params are derived as follows.
period = max(25TU, beacon interval / number of bss)
duration = period * duty cycle / 100
Quiet mode can be disabled by setting the duty cycle to 0. The cooling
device can be found under /sys/class/thermal/cooling_deviceX/.
Corresponding soft link to this device can be found under phy folder.
/sys/class/ieee80211/phy*/device/cooling_device.

Firmware doesn't allow precise tx rate control so
P2P wasn't entirely spec compliant (it was using
CCK rates in some cases).
The only way to make sure firmware doesn't use CCK
rates is to have a vdev with P2P subtype used for
scanning and tx. This can be done via a special
dedicated P2P device interface support.
This also removes the ancient hack from ath10k in
