ath10k: set max_num_vdevs based on wmi op version

To make it easier to manage firmware differences, we should not use
ATH10K_FW_FEATURE_WMI_10X outside ath10k_core_init_firmware_features(). To
achieve that create new field ar->max_num_vdevs and set it based on wmi op
version.

ath10k: use wmi op version to check which iface combination to use

ATH10K_FW_FEATURE_WMI_10X should not be used for anymore as that's
now deprecated, instead use wmi op version.

ath10k: print ath10k wmi op version

The internal firmware version doesn't tell much to the user, it's more
informative to use that field to print the wmi op version.

ath10k: add 10.2.4 firmware support

10.2.4 firmware uses bitmask in wmi_resource_config to configure
10.2 firmware features like airtime fairness and rx batch mode instead
of maintaining separete bool entry. This allows new features that can be
configure during init time without breaking backward compatibility.

kvalo: use WMI op version, bump up FW API to 4 to not break older versions of
ath10k

ath10k: add wmi support for pdev_set_quiet_mode

Add WMI support to send pdev_set_quiet_mode command to target.
This will be used for thermal mitigation purpose.

ath10k: add thermal cooling device support

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.

To set duty cycle as 40%,

echo 40 >/sys/class/ieee80211/phy*/device/cooling_device/cur_state

ath10k: add wmi interface for pdev_get_temperature

Add WMI command support for reading temperature from the target and
corresponding WMI temperature event handler. The pdev_get_temperature
command is currently supported in 10.2 firmware alone.

ath10k: add thermal sensor device support

Temperature sensor generates electrical analog voltage from temperature
of each chain. The analog voltage is converted to digital value through
ADC. For reading temperature values fom user space, hw monitoring device
is used.

Whenever the user requests for current temperature, the driver sends WMI
command and wait for response. For reading temperature,

cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input

ath10k: send (re)assoc peer command when NSS changed

Assoc peer command contain information about NSS.
When we will get IEEE80211_RC_NSS_CHANGED we should
also send (re) assoc peer command to be sure firmware
will know about it and RC will work correctly.

This was found during code review.
