arm64: dts: imx93: Add i.MX93 Wireless EVK board support

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
imx93-11x11-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)
	  SPI_TXD	SAI1_TXC (spi1.SIN)	GPIO_IO09 (spi3.SIN)
	  SPI_RXD	SAI1_RXD0 (spi1.SOUT)	GPIO_IO10 (spi3.SOUT)
	  SPI_CLK	SAI1_TXD0 (spi1.SCK)	GPIO_IO11 (spi3.SCK)
	  SPI_INT	CCM_CLKO1		on-board IO expander
	  NB_WAKE_IN	PDM_CLK			on-module IO expander
	  WL_WAKE_IN	PDM_BIT_STREAM0		on-module IO expander
	  IND_RST_WL	PDM_BIT_STREAM1		on-module IO expander
	  IND_RST_NB	GPIO_IO28		on-module IO expander
	  PDn		GPIO_IO29		on-module IO expander
	  NB_WAKE_OUT	GPIO_IO14		on-board IO expander
	  WL_WAKE_OUT	GPIO_IO15		CCM_CLKO1
I2C3	  I2C3_SDA	GPIO_IO00		GPIO_IO28
	  I2C3_SCL	GPIO_IO01		GPIO_IO29
