eeprom: Remove unused argument from size method

There's not much value in having the extra eeprom argument, and
getting rid of it will make it easier to use generic functions to
obtain ROM size (without requiring trivial wrappers).

BUG=none
BRANCH=none
TEST=compiled for x86 and ARM platforms, "mosys eeprom" commands
still work on cyan
