Revert "drivers: mfd: Return EPROBE_DEFER during codec failure"

This reverts commit 96913bef9307 ("drivers: mfd: Return EPROBE_DEFER during
codec failure"). If target can support multiple codecs,
one of the codec enumerates. When other codec fails to enumerate,
donot return -EPROBE_DEFER otherwise probe is triggered again
which is cleaning common resources and hence enumerated
codec is going to bad state.
