link: disable unused EEPROM modules

Haven't found a use for these, so remove to reduce code size (reduces
binary by 2KB) / complexity.

These are still test-compiled on BDS so they'll be ready if needed.

BUG=chrome-os-partner:11232
BRANCH=link
TEST=build and boot firmware.  'help' should not show eeread/eewrite commands
