Subject[PATCH 2/5] leds: make sure leds_class is initialized before triggers are registered
If the led-class and usb-common modules are built into the kernel, the
usb-common module could be initialized earlier than the led-class module.

So when the ledtrig_usb_gadget and ledtrig_usb_host LED triggers are
registered by usb-common module, the leds_class could not be initialized

We are going to populate sub-directories, each representing an LED
trigger in /sys/class/triggers/, so leds_class needs to be initialized
before any LED triggers is registered.

This makes led-class initialize earlier then usb-common by changing
initcall group.
