sysfs entry for mceusb and streamzap

[Paul B. <peb...@gm...>]

When trying to create persistent device names for mceusb and streamzap 
devices, I noticed that their respective drivers are not creating the rc 
device as a child of the USB device. Rather it creates it as virtual 
device. As a result, udev cannot use the USB device information to 
create persistent device names for event and lirc devices associated 
with the rc device. Not having persistent device names makes it more 
difficult to make use of the devices in userspace as their names can change.

I have attached a patch that fixes it for me.
