[PATCH] commands: of_diff: don't mix tabs and spaces for indentation

[PATCH] commands: of_diff: don't mix tabs and spaces for indentation

[Ahmad Fatoum]

Nodes are indented with spaces, while properties are indented with tabs,
leading to discrepancies when the indentation doesn't start at a tab
stop, like when using of_diff:

chosen {
+ 	barebox-version = "barebox-2021.06.0-20210716-2";
+ 	reset-source = "POR";
+ 	reset-source-instance = <0x0>;
+        subnode {

Fix this by using spaces throughout.
