arm: dts: add/fix I2C controllers for sc5xx

Browse Source 
sc59x processors have 6 I2C controllers, but their devicetrees
currently have only 3. The length of its register block should
be 0x100 instead of 0x1000. All I2C nodes should be disabled in
sc5xx.dtsi. They can be enabled in board devicetree files if
they are used on the boards. Add missing I2C controllers and
fix the above issues.
