Enable Bluetooth and WiFi connectivity on Shikra CQM, CQS and IQS
EVK boards using the WCN3988 combo chip.

For Bluetooth, enable uart8 and add WCN3988 Bluetooth node with
board-specific regulator supplies across CQM, CQS and IQS Shikra
EVK boards.

For WiFi, introduce the wcn3990-wifi hardware node in shikra.dtsi
with register space, interrupts, IOMMU configuration and reserved
memory. The node is kept disabled by default and enabled per-board
with the appropriate PMIC supply connections and calibration variant
selection.

Split the SoC and board changes

Sure, i will the changes.


Should most of the board-level changes go to evk.dtsi, since
they're almost identical across all boards? You can e.g. simply
override the supplies in the IQS EVK DTS

For wcn3988-pmu node, I can move it to shikra-evk.dtsi and add the supplies in the board DTS files. However, this approach will be subjective to per node, as other nodes (such as sound) have board-specific changes beyond just supplies.

Thanks
Komal
