fbdev: sh_mobile_hdmi: modify flags name to more specific

This patch solve below report from Guennadi

1)

> +/* Audio source select */
> +#define HDMI_SRC_MASK		(0xF << 0)
> +#define HDMI_SRC_I2S		(0 << 0) /* default */
> +#define HDMI_SRC_SPDIF		(1 << 0)
> +#define HDMI_SRC_DSD		(2 << 0)
> +#define HDMI_SRC_HBR		(3 << 0)

I would be more specific with these macro names, i.e., include "AUDIO" or
"SND" or something similar in them, e.g., HDMI_AUDIO_SRC_I2S.

2)

> +	case HDMI_SRC_I2S:
> +		data = (0x0 << 3);
> +		break;
> +	case HDMI_SRC_SPDIF:
> +		data = (0x1 << 3);
> +		break;
> +	case HDMI_SRC_DSD:
> +		data = (0x2 << 3);
> +		break;
> +	case HDMI_SRC_HBR:
> +		data = (0x3 << 3);

In all above cases parenthesis are superfluous.
