ramips: use gpio-export for Mikrotik RouterBOARD 750Gr3 beeper

This beeper hardware requires a PWM driver for frequency selection.
Since the GPIO driver does not provide that, revert the beeper
support to a simple gpio-export.

This effectively reverts the corresponding changes from
6ba58b7b020c ("ramips: cleanup the RB750Gr3 support")
