Add device tree overlay to support the MayQueen PixPaper e-paper display
on the NXP i.MX93 FRDM board. The display is connected via LPSPI3
interface and uses GPIO pins for reset, busy and DC control.

The overlay configures:
   - LPSPI3 pinmux for SPI communication (MOSI, MISO, CLK, CE0)
   - PixPaper display device with proper GPIO assignments
   - SPI frequency set to 5MHz for stable operation

Enable Open-EP Community pixpaper-213-c support on NXP i.MX93.

Hi reviewers,

Thanks to Peng for the review.

Just a gentle ping on this patch.
Please let me know if any further reviews or changes are needed.

There are CHECK_DTBS warning

arch/arm64/boot/dts/freescale/imx93-11x11-frdm-pixpaper.dtb: display@0 (mayqueen,pixpaper): spi-max-frequency: 5000000 is greater than the maximum of 1000000
	from schema $id: http://devicetree.org/schemas/display/mayqueen,pixpaper.yaml

Does 1000000 work for spi-max-frequency? or need update binding doc?

Frank

Thanks,
Wig
