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.

The duty cycle (% of quiet duration) is used to put the device
in quiet mode for the given period. Currently the quiet duration
is wrongly calculated which results in not enabling quiet mode.
Fix the calculation as below

     duration = (period * duty cycle) / 100

When replenishing Rx buffers driver updates the address of the

Change in order by CPU can cause rx ring corruption. Add memory

Major changes in ath10k:

* Device tree support

* Major restructuring how to handle different WMI interface versions

* Add WMI TLV interface in preparation for new firmware interface support

* Support new firmware branch 10.2.4

* Add thermal cooling interface

* Add hwmon interface to read temparture from the device

And of course lots of small fixes and cleanups.
