[PATCH] ASoC: Make SND_SOC_SAARB and SND_SOC_TAVOREVB3 selectMFD_88PM860X

[Axel Lin]

In saarb_pm860x_init() and evb3_pm860x_init(), we call
pm860x_hs_jack_detect() and pm860x_mic_jack_detect() which in turn
calls pm860x_set_bits().
Thus make SND_SOC_SAARB and SND_SOC_TAVOREVB3 select MFD_88PM860X.

This patch fixes below build error if CONFIG_MFD_88PM860X is not configured.
