The I2C function of the RT5350 SoC on the HLK-RM04 is used for GPIO1 and GPIO2.
Take note that the I2C_SD pin is GPIO1 on the RT5350 and is exposed on the HLK-RM04 as GPIO0
Likewise the I2C_SCLK pin is GPIO2 on the RT5350 and is exposed on the HLK-RM04 as GPIO1
group mode 1 mode 2 hlk-rm04 pin & export
i2c i2c_sd gpio1 (pin 8, hlk-rm04:gpio0)
i2c i2c_sclk gpio2 (pin 9, hlk-rm04:gpio1)

The power LED on the HLK-RM04 is hard wired to the power bus and is not under GPIO control, remove the bogus config for it.
(Note that GPIO0 is actually connected to the RESET button.)

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?).
