imx8qxp_android11去除M4相关的编译

使用imx8qxp官方代码：
编译完成后uboot的log显示

0

下面一大堆Disabled的相关的东西。
后面调试后发现，我与这些对应的Disabled的东西，比如 i2c@37230000和imx8x_cm4@0相关的东西，在kernel设备树里面进行配置后无法枚举，也不会去加载驱动。对应的外设也不能沟调试。
后面自己去查看了一下，nxp上对应的问题是android11里面有M4对应的处理器，如果编译了M4对应的一些资源就会被M4占有，我将无法控制。
以前每玩过IMX8QXP也没遇到这种，后面一咬牙一跺脚，直接去修改了他的脚本。

修改后uboot的 log显示：

成功了。

修改后的问题，使用sudo ./uuu_imx_android_flash.sh -f imx8qxp -e -u c0命令无法一次烧录成功。
需要先执行命令：

sudo uuu -b emmc flash.bin

这个会显示失败！（flash.bin在vendor/nxp-opensource/imx-mkimage/iMX8QX目录下生成）自己拷贝过来。

问题不大，不用理他，再次执行命令

sudo ./uuu_imx_android_flash.sh -f imx8qxp -e -u c0

哒哒！先这样自己调外设吧。后面在去解决这个M4的问题。
