I am running a much older kernel (4.1 LTS) but it seems you have
everything. I did find your problem though, although I have no idea how
to fix it:

[ 7.185141] hid-generic 0003:0471:0613.0003: input,hiddev0,hidraw2: USB
HID v1.00 Keyboard [PHILIPS MCE USB IR Receiver- Spinel plus] on
usb-0000:04:00.0-2/input0

The kernel is registering your device as a keyboard (incorrectly,
obviously.) Presumably this is why it is not creating /sys/class/rc/rc0.
I would assume you'd have to block Xorg from seeing it as a keyboard and
maybe write a udev rule to register the device correctly?

On my mythtv frontend my device (an iMon device) registers correctly as
an IR device:

[    7.000121] input: iMON Remote (15c2:0038) as
/devices/pci0000:00/0000:00:1a.2/usb5/5-1/5-1:1.0/rc/rc0/input6


I did a quick Google for your device and "keyboard" and this thread
looks promising:

http://forum.kodi.tv/showthread.php?tid=133071&pid=1118999#pid1118999

You might be able to get some information there to stop it from
registering itself as a keyboard. This is for Ubuntu or one of its
forks, so you may have to adjust things accordingly.

Sorry I wasn't much help.
