arm64: dts: imx943-evk-sdwifi: add a new dtso to support SDIW612 WiFi

Browse Source 
Add a new imx943-evk-sdwifi.dtso to support SDIW612 WiFi chip on
imx943-evk board, the default imx943-evk.dtb is used to support PCIE
AW693 WiFi.

Use separate dts for SDIW612 and PCIe AW693 WiFi to avoid the shared
regulator between SDIO and PCIe buses, the random probe order between
the two buses may break the PCIe initialization sequence which cause
AW693 has probability of failing to detect.
