[PATCH] arm64: defconfig: enable regulator to fix mt8173 regression

[Adrian Ratiu]

A regression was introduced on some mediatek boards starting with
v5.15-rc1 in commit 109fd20601e2b ("arm64: dts: mediatek: mt8173:
Add domain supply for mfg_async") which effectively changed the
regulator from the always-on dummy to DA9211 without explicitely
enabling it, causing failures like the these caught by KernelCI
on Hana Chromebooks [1]:

mtk-power-controller 10006000.syscon:power-controller: supply domain not found, using dummy regulator
mtu3 11271000.usb: supply vbus not found, using dummy regulator
xhci-mtk 11270000.usb: supply vbus not found, using dummy regulator

There might be another bug linking these power domains in the
mediatek PM driver, but that is a separate issue wich needs
addressing, for now just fix the obvious regression due to the
new regulator requirement.
