[Impact]
PMIC_OPREGION is required to make GFX works on Bay Trail and Cherry
Trial based tablets.

[Fix]
Enable CONFIG_PMIC_OPREGION.
CONFIG_GPIO_CRYSTAL_COVE needs to be loaded before i915 to control
panel, so change it to builtin.

These configs are aligned with Fedora kernel.

[Test]
The i915 can now kinda work albeit hitting another bug. That's a
different issue though.

[Regression Potential]
Low. These configs only affects Intel-based budget tablets, GFX never
worked.
It's a bit late for Focal so only enable configs in Unstable.
