i.MX93 Wireless SiP is created by integrating i.MX93 and IW610 WLCSP
(Wi-Fi + BLE + 802.15.4). And i.MX93 Wireless EVK board with the
i.MX93 Wireless SiP basically reuse the i.MX93 11x11 EVK board, with
some minor functional and pin connection differences. Reuse the new
imx93-evk-common.dtsi and add the board-specific changes here.

Here are the detailed differences between i.MX93 Wireless EVK and
i.MX93
11x11 EVK board.

Function differences:
Function	i.MX93W EVK			i.MX93 EVK
WIFI/BT		IW610 in i.MX93W		IW612 M.2 module
MQS		N				Y
PDM MIC		N				Y
M.2		N				Y
RPi 40-pin HDR	Limited support(pin conflict) 	Y

Pin connection differences:
Function  Signal name	i.MX93W EVK		i.MX93 EVK
WIFI/BT	  SPI_FRM	SAI1_TXFS (spi1.PCS0)	GPIO_IO08

(spi3.PCS0)

keep alphabet order

Sure, will do in V5.

Put &lpi3c node here, which use below pin mux.

It's difficult to move the full lpi2c3 node into imx93w-evk.dts and
imx93-11x11-evk.dts separately because lpi2c3 contains several
child nodes (adp5585_isp, ptn5110, ptn5110_2, pcf2131).

All of these child nodes share exactly the same DTS configuration
on both boards. The only difference between the two EVKs is the
pinctrl_lpi2c3. Given that the whole lpi2c3 hierarchy (including child
nodes) is identical across these boards, keeping the common lpi2c3
configuration in imx93-evk-common.dtsi makes the structure clearer
and avoids duplication.

In this case, i.MX93 Wireless EVK board DTS only needs to override
pinctrl_lpi2c3, which keeps the DTS layout clean.
