Subject: [PATCH v2 1/2] ARM: dts: bcm23550: Add SoC-specific I2C compatible

Add BCM23550-specific compatible for brcm,kona-i2c nodes. While not
currently used by the i2c-bcm-kona driver, they can serve for further
customization, if required.
Done in preparation for dt-binding coversion to DT schema.
