dt-bindings: input: exc3000: move eeti,egalax_ts from egalax-ts.txt to eeti,exc3000.yaml
Remove legacy binding egalax-ts.txt file. And add compatible string
eeti,egalax_ts and wakeup-gpios to eeti,exc3000.yaml. "eeti,egalax_ts" is
general compatible string, which is not preferred. But it is compatible
with old devices (older than 10 years) and existing driver in
drivers/input/touchscreen/egalax_ts.c.
Allow address 0x4 for eeti,egalax_ts.
Don't require touchscreen-size-x(y) for eeti,egalax_ts.
Keep the same restriction for existing compatible string.
Fix below DTB_CHECKS warnings:
arch/arm/boot/dts/nxp/imx/imx6dl-gw52xx.dtb: /soc/bus@2100000/i2c@21a8000/egalax_ts@4: failed to match any schema with compatible: ['eeti,egalax_ts']
