[PATCH 2/6] ASoC: soc-pcm: add dpcm_set_be_update_state()

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

soc-pcm has dpcm_set_fe_update_state() to update FE's runtime_update
(except dpcm_fe_dai_do_trigger() which needs to update it without it).
OTOH, it doesn't have BE's update function.

	O: dpcm_set_fe_update_state()
	X: dpcm_set_be_update_state()

This patch add BE's dpcm_set_fe_update_state()
