3.13-stable review patch. If anyone has any objections, please let me know.

commit 8eeb5c15131d7b5061c10423eda3ae4c68db4eaf upstream.
The 88pm860 is a MFD device and the CODEC driver is using the regmap struct of the parent device, hence automatic IO setup will not work and we need to manually call snd_soc_codec_set_cache_io(). The issue was introduced in commit f9ded3b2e7 ("ASoC: 88pm860x: Use regmap for I/O").
