[RESEND PATCH] mfd: sc27xx: Use SoC compatible string for PMIC devices

We should use SoC compatible string in stead of wildcard string for PMIC child devices. Signed-off-by: Baolin Wang --- Hi Lee, Could you merge this patch into v5.1-rc if no objection from you? Since our DTS patches had been merged into v5.1, our PMIC can not work without this patch. Thanks
