fix(servo): Add missing component requirements

[meanwhile131]

Description

Building examples/motor/servo_control currently fails (both on my machine and a fresh Github Codespaces environment) because the motor/servo component doesn't have all the required components in REQUIRES
Build log: https://gist.github.com/meanwhile131/5b9da50c992071d18938baa58dd21ff1

Adding esp_driver_ledc and esp_driver_gpio to REQUIRES as idf.py build suggested fixes the build.

Testing

Built examples/motor/servo_control and components/motor/servo/test_apps in a clean Github Codespace on latest ESP-IDF (installed via eim install)

Hi, @meanwhile131 ,Thank you very much for your contribution. You can refer to this commit to add some compatibility for the IDF version.

The README says that the master branch is for IDF >= 5.3. Should we really maintain compatibility with older versions for new changes?

The README document provides guidance on the components of the repository. The specific supported IDF versions are determined by each individual component. Even if a lower IDF version is maintained for a long time for compatibility, it will not be rejected.
