mac80211: ath12k: backport thermal sensor support

This is nearly identical to what landed in ath-next for v7.1, aside from
resolving a couple conflicts. A separate patch has been added to replace
CONFIG_THERMAL with CPTCFG_ATH12K_THERMAL so the setting may be enabled
via menuconfig (as is done with ath10k and ath11k).

Note that at this stage, throttling has not been implemented upstream,
hence the slight change in wording versus existing options.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
