issue when the PR is merged.
If you are adding/modifying/removing any command or utility script, please also
make sure to add/modify/remove any unit tests from the tests
directory as appropriate.
If you are modifying or removing an existing 'show', 'config' or 'sonic-clear'
subcommand, or you are adding a new subcommand, please make sure you also
update the Command Line Reference Guide (doc/Command-Reference.md) to reflect
your changes.

#### What I did
Return DOM for flat memory modules if it's available.
#### How I did it
Removed the conditional which skipped returning DOM for flat memory modules when using `sfputil show eeprom -d -p <interface>` command.
#### How to verify it
Run `sfputil show eeprom -d -p <interface>` for a flat memory module.
#### Previous command output (if the output of a command-line utility has changed)
Previously, `sfputil show eeprom -d -p <interface>` for a flat memory module would have `DOM values not supported for flat memory module` in the end and no DOM would be printed.
#### New command output (if the output of a command-line utility has changed)
Now, the command returns the DOM for flat memory modules if it's available.
CLI output for a flat memory transceiver now:
