HID: blacklist Powercom USB UPS

For quite some time users with various UPSes from Powercom were forced to play
magic with bind/unbind in /sys in order to be able to see the UPSes.  The
beasts does not work as HID devices, even if claims to do so.  cypress_m8
driver works with the devices instead, creating a normal serial port with which
normal UPS controlling software works.

The manufacturer confirmed the upcoming models with proper HID support will
have different device IDs.  In any way, it's wrong to have two completely
different modules for one device in kernel.

Blacklist the device in HID (add it to hid_ignore_list) to stop this mess,
finally.
