Move reset to DisplayModeTrait

The functionality is common, so the implementation can be as well.

Hi! Thank you for helping out with SSD1306 development! Please:

• [ ] Check that you've added documentation to any new methods
• [ ] Rebase from master if you're not already up to date
• [ ] Add or modify an example if there are changes to the public API
• [ ] Add a CHANGELOG.md entry in the Unreleased section under the appropriate heading (Added, Fixed, Changed, etc)
• [ ] Run rustfmt on the project with cargo fmt --all - CI will not pass without this step
• [ ] Check that your branch is up to date with master and that CI is passing once the PR is opened

PR description

Just a bit of cleanup. Should be backwards compatible since the trait is in the prelude. I don't think there should be a changelog entry for this one.

Fair enough. I also marked it as breaking

[bugadani]

No worries, thanks for accepting my contributions :)

Any time!
