wifi: ath12k: Avoid CPU busy-wait by handling VDEV_STAT and BCN_STAT
When the ath12k driver is built without CONFIG_ATH12K_DEBUG, the
recently refactored stats code can cause any user space application
(such at NetworkManager) to consume 100% CPU for 3 seconds, every time
stats are read.
Commit 'b8a0d83fe4c7 ("wifi: ath12k: move firmware stats out of
debugfs")' moved ath12k_debugfs_fw_stats_request() out of debugfs, by
merging the additional logic into ath12k_mac_get_fw_stats().
Among the added responsibility of ath12k_mac_get_fw_stats() was the
busy-wait for `fw_stats_done`.
Signalling of `fw_stats_done` happens when one of the
WMI_REQUEST_PDEV_STAT, WMI_REQUEST_VDEV_STAT, and WMI_REQUEST_BCN_STAT
messages are received, but the handling of the latter two commands remained
in the debugfs code. As `fw_stats_done` isn't signalled, the calling
processes will spin until the timeout (3 seconds) is reached.
Moving the handling of these two additional responses out of debugfs
resolves the issue.
Fixes:

wifi: ath12k: Add support for link specific datapath stats
Add support to record the number of frames enqueued, hardware descriptor type, encapsulation/encryption types used, frames dropped and completed. This is useful for understanding the datapath performance and tune the peak throughput.

wifi: ath12k: move firmware stats out of debugfs
Currently, firmware stats, comprising pdev, vdev and beacon stats are part of debugfs. In firmware pdev stats, firmware reports the final Tx power used to transmit each packet. If driver wants to know the final Tx power being used at firmware level, it can leverage from firmware pdev stats. Move firmware stats out of debugfs context in order to leverage the final Tx power reported in it even when debugfs is disabled.

wifi: ath12k: Add Support to Calculate and Display TPC Values
Transmit Power Control(TPC) stats should display per chain TPC value per
radio. Add debugfs support to read and display TPC stats type and TPC
stats. Take power values for each preamble type, rate and NSS combination
from a particular index from each power arrays based on number of chains,
NSS, modes, MCS and tx beamforming enabled/disabled parameters. Minimum
of the values taken from reg power table, rates and Conformance Test
Limit(CTL) array table should give the TPC which is in 0.25 dBm steps.

wifi: ath12k: Add Support to Parse TPC Event from Firmware
Host receives four Transmit Power Control(TPC) events from firmware on sending TPC request. Fixed param TLV is present as part of all event to indicate the event count and end of event. TPC config parameters along with regulatory power array comes as first event. Rates array comes as second and third event as it cannot be packed in single event. Conformance Test Limit (CTL) power array comes as the fourth event. Firmware packs different sets of array params which includes array length and type inside master TLV as different subtlvs. And the actual content of array is packed one after the other inside a separate TLV as single buffer. Parse various events and save it in local structures. Create tpc_stats file using debugfs to store these local structures. Create function to handle TPC stats read to relay the information to the user.
