Similar to what we have on other Amlogic boards this adds the
gpio-line-names to Odroid-C1.
This makes it easy to compare the schematics with the actual .dts
configuration by looking at the debugfs GPIO file.

This adds the GPIO line names from the schematics to get them displayed
in the debugfs output of each GPIO controller.
The schematics from Odroid-C1+ PCB revision 0.4 20150615 are used as
referenced.
