V4L/DVB (13536): em28xx: Use the full RC5 code on HVR-950 Remote Controller

Modifies the IR table for HVR-950 to use the newer Hauppauge RC5 table,
and adds the RC5 address to the functions that get the scancode for this
device.

It is easy to add support for all other RC5 IR's on em2880 boards, but
the scancode table needs to be re-generated. So, keep using the old
7bits tables while we don't have all tables converted.

Also, the 7bits tables are still used on other drivers, so this small
patch needs to be ported to all drivers.
