[PATCH v3] i2c: eeprom: Use reg property instead of offset and size

Remove adhoc dt binding for fixed-partition definition for i2c eeprom. fixed-partition are using reg property instead of offset/size pair.

Changes in v3: - Add test for sandbox - Fix issues related to OF_TRANSLATE - Remove address/size cells from parent because of OF_TRANSLATE
Changes in v2: - Bootcount tested on zynqmp zcu104 - Add missing address/size cells - Use dev_read_addr_size_index - Check parameters
Just build tested - ge_bx50v3_defconfig Tested on zcu104
