The ST M24256E behaves as a regular M24C256, except for the E variant which uses up another I2C address for Additional Write lockable page. This page is 64 Bytes long and can contain additional data. Add entry for it, so users can describe that page in DT. Note that users still have to describe the main M24C256 area separately as that is on separate I2C address from this page. Unlike M24C32-D and M24C64-D, this part is specifically ST and does not have any comparable M24* counterparts from other vendors, hence the st, vendor prefix. Furthermore, the part name is M24256E without C between the 24 and 256, this is not a typo. Finally, there is M24C256-D part, which does contain 32 Bytes long Additional Write lockable page, which is a different part and not supported by this patch.
