Latest fails to detect camera on Luckfox Ultra

[jlunn-tactacam]

The latest build defaults to i2c4_m0 instead of i2c4_m2 for Luckfox Ultra non-tb builds.

Steps to reproduce:

./build.sh lunch
ls: cannot access 'BoardConfig*.mk': No such file or directory
You're building on Linux
  Lunch menu...pick the Luckfox Pico hardware version:
  选择 Luckfox Pico 硬件版本:
                [0] RV1103_Luckfox_Pico
                [1] RV1103_Luckfox_Pico_Mini_A
                [2] RV1103_Luckfox_Pico_Mini_B
                [3] RV1103_Luckfox_Pico_Plus

on boot the log message shows i2c conflict and i2c4m0-xfer instead of i2c4m2-xfer

Hello, since both the camera and GPIO have I2C4 pins, in order to allow luckfox-config to successfully control i2C4m0-xfer, the pinctrl information of i2c4 in the device tree will contain multiple sets of i2c4 pins, so the error message can be ignored.
The camera does not turn on automatically on the Luckfox Pico Ultra/Ultra W, you need to run luckfox-config -> Advanced Options -> CSI -> enabled after entering the system
