If it's fine to have the 3G modem enabled all the time, please add a 
gpio-export node to your device tree source file. The same is done to 
enable usb power for some boards. Have a look at 
https://git.lede-project.org/?p=source.git;a=blob;f=target/linux/ramips/dts/DIR-645.dts;hb=4f1ff28f086da25b122cc29c4c468a33eb7ec891#l128 
for an example.
