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

From: Vasily Khoruzhick <anarsoul@gmail.com>

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.

Fixes: 5f0acedddf533c (ASoC: rx1950_uda1380: Use static DAI format setup)
Fixes: 5cc10b9b77c234 (ASoC: h1940_uda1380: Use static DAI format setup)
