- Patch 1/4 Add description of the PMU of the WCN6750 module.
- Patch 2/4 add and enable BT node for qcs6490-rb3gen board.
- Patch 3/4 use the power sequencer for wcn6750.
- Patch 4/4 add support for the WCN6750 PMU.

----
Changes from v4:
* Added reviewed tag by Krzysztof in p1
* Updated the p2 commit message with sw_ctrl and wifi-enable are
  handled in wifi FW.
* Added blank line between the nodes in p2
* Placed the structures in proper order in p4
* Link to v4: https://lore.kernel.org/all/20241204131706.20791-1-quic_janathot@quicinc.com/

Changes from v3:
* Defined the PMU node and used the its output to power up BT
* Used power sequencer for wcn wcn6750 module
* Split the patch to multiple as per subtree
* Add description of the PMU of the WCN6750 module
* Include separate UART state node for sleep pin configuarion
* Link to v3: https://lore.kernel.org/linux-arm-msm/20241022104600.3228-1-quic_janathot@quicinc.com/

Changes from v2:
* Sorted nodes alphabetically
* Link to v2: https://lore.kernel.org/linux-arm-msm/20241010105107.30118-1-quic_janathot@quicinc.com/

Changes from v1:
* Corrected the board name in subject
* Link to v1: https://lore.kernel.org/linux-arm-msm/20241009111436.23473-1-quic_janathot@quicinc.com/

In WCN6750 module sw_ctrl and wifi-enable pins are handled

to have those pins' entries in the PMU node.

We are now using the on-chip PMU node for power sequencing to manage the
enable/disable functionality of Bluetooth. Consequently, the inputs
previously marked as required under the Bluetooth node can be removed.

For instance, the enable GPIO is now managed by the PMU node with the
property bt-enable-gpios.

Drop the inputs from the host and instead expect the Bluetooth node to
consume the outputs of the internal PMU.
