rk27generic: FM radio screen keys, tuner noted as an RDA5807P

Browse source 
The FM screen had no actions for the rk27xx generic keypad; give it those
its keymap already maps (menu, play, stop, exit) in radio.c.

The board's tuner is an RDA5807P. It keeps being driven as a TEA5767, in
the chip's compatible mode, as the original firmware does: tuning, seek
and the stereo indicator work so, and the RDA mode would bring nothing
here - this variant has no RDS. Say so next to CONFIG_TUNER.

The tuner's audio is on the codec's line input 1: only that line is
powered and mixed in while the radio plays (RK27XX_CODEC_FM_LINE 1). With
line 2 instead the radio is silent.

Tested on the rk27generic board: manual tuning, seek, stereo indicator and
audio.
