fbdev: sh_mobile_hdmi: modify snd_soc_dai_driver settings

This patch solve below report from Guennadi

Can it actually do mono? Maybe at probe time you could look at audio flags
from your previous patch and, e.g., for SPDIF set channels_min to 2?

> +		.channels_max = 2,

That's the "smallest max," yes. With some other interfaces (I2S, DSD) it
can support up to 8 channels...

> +		.rates = SNDRV_PCM_RATE_8000_48000,

Hm, in the datasheet I see supported frequencies 32kHz to 192kHz. And if
you promise support for multiple frequencies, don't you want to implement
.hw_params? Besides, not all of these frequencies will be available,
depending on your supplied clock and your willingness to implement
downsampling.
