ASoC: renesas: rz-ssi: Use only the proper amount of dividers

Browse Source 
[ Upstream commit 55c209cd43 ]

There is no need to populate the ckdv[] with invalid dividers as that
part will not be indexed anyway. The ssi->audio_mck/bclk_rate should
always be >= 0. While at it, change the ckdv type as u8, as the divider
128 was previously using the s8 sign bit.
