修复编译时的一些报错

[RadxaYuntian]

有的设备树节点缺少了比如#clock-cells的定义，会在编译时警告。这个因为dts有对应定义，实际上使用是没有问题的，但我们之后会打算增强dts的检查，所以现在先把这些简单的问题修复了

[RadxaYuntian]

按照你的修改后编译还是一大堆新的警告

[RadxaYuntian]

比如/ports: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary就应该把ports/port@0转换成单独的port结点：

你是使用什么内核？

我直接用我现在的arch内核运行make arch/arm64/boot/dts/rockchip/overlays/rock-3a-radxa-5inch-touchscreen.dtbo

[RadxaYuntian]

第一个结点的修改可能有点问题，我看看

[CodeChenL]

我这不会报错啊

第一个diff我修改了一下，另外你要pull一下你本地的代码，dtc的-q我之前删了

[RadxaYuntian]

可以反编译试一试这么改和有@0的是不是一样的结果
