media: rc: XBox DVD Remote uses 12 bits scancodes

Browse Source 
Sean Young figured out that the Xbox Remote sends 24 bits, the first 12 bits are repeated
and inverted so only 12 bits are used. Turns out this is a modified nec protocol.

For increased accuracy and compliance with the upstream, replace the historic 8 bit report
values with the proper 12 bit values.
