Kai Vehmanen 8e85def572 ALSA: hda: enable regmap internal locking 
This reverts commit 42ec336f1f ("ALSA: hda: Disable regmap
internal locking").

Without regmap locking, there is a race between snd_hda_codec_amp_init()
and PM callbacks issuing regcache_sync(). This was caught by
following kernel warning trace:

<4> [358.080081] WARNING: CPU: 2 PID: 4157 at drivers/base/regmap/regcache.c:498 regcache_cache_only+0xf5/0x130
[...]
<4> [358.080148] Call Trace:
<4> [358.080158]  snd_hda_codec_amp_init+0x4e/0x100 [snd_hda_codec]
<4> [358.080169]  snd_hda_codec_amp_init_stereo+0x40/0x80 [snd_hda_codec]
