Fix F303 audio output on A4 with the dac_basic driver (#12480)

The dac_basic driver did not work properly with `#define AUDIO_PIN A4`
(instead of configuring the A4 pin, the driver actually was switching
the A5 pin to analog mode, breaking any other usage of that pin in
addition to emitting a distorted signal on the improperly configured
A4 pin).  Fix the code to configure the A4 pin as intended.
