Subject: ASoC: uda1380: Avoid accessing i2c bus when codec is disabled

commit 810e4425c224af6be67dff68c8832af1b5a11f89 upstream.

set_dai_fmt_both() callback is called from snd_soc_runtime_set_dai_fmt()
which is called from snd_soc_register_card(), but at this time codec
is not powered on yet. Replace direct i2c write with regcache write.
