[PATCH 2/6 v3] ASoC: rsnd: move DVC_DVUER settings under rsnd_dvc_volume_update()

[Kuninori Morimoto <kuninori.morimoto.gx@gmail.com>]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

We need to Enable/Disable DVC_DVUER register if we set
DVCp_ZCMCR, DVCp_VRCTR, DVCp_VRPDR, DVCp_VRDBR,
DVCp_VOL0R, DVCp_VOL1R, DVCp_VOL2R, DVCp_VOL3R,
DVCp_VOL4R, DVCp_VOL5R, DVCp_VOL6R, DVCp_VOL7R
and, these are controlled under rsnd_dvc_volume_update().
This patch moves DVC_DVUER settings to it.
