cm-t35: fix legacy board revision representation
Legacy eeprom layout represents the revision number syntactically (i.e. revision 1.00 is written as 0x100). This is inconsistent with the representation in newer layouts, where it is defined semantically (i.e. 0x64). This patch fixes the issue by replacing the syntactic representation with the semantic one.
