ACPI / PMIC: Stop xpower OPRegion handler relying on IIO
The intel_pmic_xpower code provides an OPRegion handler, which must be available before other drivers using it are loaded, which can only be ensured if both the mfd and opregion drivers are built in, which is why the Kconfig option for intel_pmic_xpower is a bool. The use of IIO is causing trouble for generic distro configs here as distros will typically want to build IIO drivers as modules and there really is no reason to use IIO here. The reading of the ADC value is a single regmap_bulk_read, which is already protected against races by the regmap-lock. This commit removes the use of IIO, allowing distros to enable the driver without needing to built IIO in and also actually simplifies the code.
