UPSTREAM: Add power sequencing support for WCN39xx WiFi/BT chips

[yepurisiddu]

This series brings upstream power sequencing support for the WCN39xx
family of WiFi/BT chips (WCN3988, WCN3990, WCN3991, WCN3998).

The WCN39xx family incorporates a simple on-chip PMU that spreads
voltages over internal rails. Unlike later WCN devices, they have no
separate enable GPIO lines and rely on the chip to handle power
sequencing internally.

Changes:
regulator: dt-bindings: Add DT schema for qcom,wcn3990-pmu covering
the WCN39xx PMU
power: sequencing: qcom-wcn: Implement power sequencer driver support
for WCN39xx
Bluetooth: qca: Enable pwrseq as an alternative to regulators for
WCN39xx devices

If the commits are merged in upstream and being backported to 6.18, shouldn't tag be BACKPORT ?

If the commits are merged in upstream and being backported to 6.18, shouldn't tag be BACKPORT ?

No. BACKPORT indicates mainline upstream patch was changed or adapted considerably to backport
to previous kernel.
