Well, I did not need it in the past to have working sound and working
suspend to RAM. And it already works if
CONFIG_PINCTRL=y
CONFIG_DEBUG_PINCTRL=y
CONFIG_GPIOLIB=y
CONFIG_GPIO_ACPI=y
CONFIG_DEBUG_GPIO=y
are set (but no PINCTRL or GPIO drivers!).
So I'd suggest to
(a) keep your fixup patch (as things work as previously then),
(b) to have CONFIG_I2C_DESIGNWARE_BAYTRAIL select the appropriate options from
above [and CONFIG_XPOWER_PMIC_OPREGION ?] (or depend on it?), or
(c) (probably best) both.

Well, I've reverted your fixup patch locally and enabled all drivers that I
could -- including CONFIG_XPOWER_PMIC_OPREGION, CONFIG_MFD_AXP20X, and
CONFIG_MFD_AXP20X_I2C. But I'm not sure at all that a driver actually became
active...
