i2c: rework kernel config I2C_ACPI
Commit da3c6647(I2C/ACPI: Clean up I2C ACPI code and Add CONFIG_I2C_ACPI config) adds a new kernel config I2C_ACPI and make I2C core built in when the config is selected. This is wrong because distributions etc generally compile I2C as a module and the commit broken that. This patch is to rename I2C_ACPI to ACPI_I2C_OPREGION. New config only controls ACPI I2C operation region code and depends on I2C=y.
