V4L/DVB (13546): ir-keymaps: Add table for Terratec Cinergy XS FM

This IR uses NEC protocol, with address=0x14. This keymap is similar
to the existing Terratec Cinergy XS, except that:
	- it contains the full address/command code;
	- the Music button were mapped as KEY_RADIO;
	- some keycodes from the previous entry were wrong, IMHO.
