ASoC: CX20442: fix NULL pointer dereference

The CX20442 codec driver never provided the snd_soc_codec_driver's
.reg_cache_default member. With the latest ASoC framework changes, it
seems to be referred unconditionally, resulting in a NULL pointer
dereference if missing. Provide it.

Created and tested on Amstrad Delta against linux-2.6.38-rc2
