[PATCH 1/2] ACPI / PMIC: Add i2c address for thermal control

On Asus T101HA, we keep receiving those error messages:

i915 0000:00:02.0: [drm] *ERROR* mipi_exec_pmic failed, error: -95
intel_soc_pmic_exec_mipi_pmic_seq_element: Not implemented
intel_soc_pmic_exec_mipi_pmic_seq_element: i2c-addr: 0x5e reg-addr 0x4b value 0x59 mask 0xff

Because the opregion is missing the I2C address.
