Fix ARM Audio issues and its EEPROM persistence (#4936)

* Don't click if turning audio off

On ARM, playing the click when turning off audio causes the audio get stuck and continually play the tone

* Fix Audio EEPROM support for ARM

* Update touched files to conform to QMK Coding Conventions

* Add better check for ARM EEPROM support
