Subject: [PATCH 5/5] ACPI / PMIC: mfd: intel_pmic_chtwc: This driver must always be builtin

The chtwc PMIC provides an ACPI 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.

This fixes errors like these during boot:

mmc0: SDHCI controller on ACPI [80860F14:00] using ADMA
ACPI Error: No handler for Region [REGS] (ffff93543b0cc3a8) [UserDefinedRegion] (20170119/evregion-166)
ACPI Error: Region UserDefinedRegion (ID=143) has no handler (20170119/exfldio-299)
ACPI Error: Method parse/execution failed [\_SB.PCI0.I2C7.PMI5.GET] (Node ffff93543b0cde10), AE_NOT_EXIST (20170119/psparse-543)
ACPI Error: Method parse/execution failed [\_SB.PCI0.SHC1._PS0] (Node ffff93543b0b5cd0), AE_NOT_EXIST (20170119/psparse-543)
acpi 80860F14:02: Failed to change power state to D0
