ramips: fix indentation and other mistakes in .dts{, i} files

The following patch fixes:
 * wrong indentations
 * doubled gpio-keys-polled nodes (DIR-300-B7, DIR-320-B1, DIR-610-A1)
 * duplicate spacings
 * empty lines at end of files and after last child nodes
 * trailing and leading whitespace
 * unnecessary and commented-out code
 * missing empty lines between nodes and between properties and nodes
 * unnecessary empty lines between nodes properties [1]

in .dts{,i} files, for ramips target.

[1] Some of empty lines in SOCs dtsi files were left untouched, because they seem to be there for a reason (readability?).
