This adds the missing properties to the PWR LED for the RPi 3 & 4 boards,
which are already set for the other boards. Without them we will lose
the LED state after suspend.

Tested on a 3B+ and a 4B. On a related note it seems that the original
RPi3B is missing the pwr led entry altogether, is that expected given
that at least the 2, other 3 models have the entry?

This is expected since the PWR LED on the 3B doesn't have a real
dedicated GPIO. In downstream this is handled via a virtual GPIO driver
which isn't available in mainline.

Best regards
