Subject: [PATCH 3/5] mfd: axp20c-i2c: Select designware i2c-bus driver on x86

On x86 the axp288 PMIC provides an ACPI OPRegion handler, which must be
available before other drivers using it are loaded, which can only be
ensured if the mfd, opregion driver and i2c-bus drivers are built in.

The opregion driver is a bool depending on MFD_AXP20X_I2C ensuring that
it will be builtin if the opregion driver is to be enabled, add a
select for the designware-options to ensure those get built in too.
