media: cx88: add IR remote support for NotOnlyTV LV3H



The PCI hybrid card NotOnlyTV LV3H has a built-in IR receiver connected
via I2C bus, currently not supported. This receiver is probably present
in more Geniatech cards. It has no capability for repeating when a key is
held down.

Add support for this built-in IR receiver. Use the existing Total Media
In Hand_02 remote keytable (Geniatech Mygica X8507) which matches exactly
the LV3H remote.
