The Crystal Cove PMIC provides an ACPI OPRegion handler, which must be available before other drivers using it are loaded, which is why INTEL_SOC_PMIC is a bool.
Just having the driver is not enough, the driver for the i2c-bus must also be built in, to ensure this, this patch adds a select for it. While at it this patch also changes the human readable name of the Kconfig option to make clear the INTEL_SOC_PMIC option selects support for the Intel Crystal Cove PMIC and documents why this is a bool.
