misc: earjack_debugger: Add earjack debugger

Analog switch for Headset and UART has crosstalk issue. It makes a noise
when using headset due to messages via uart. So only enable the uart console
to avoid crosstalk issue when using earjack debugger

This driver controls the uart console enable/disable.
