soc/amd/stoneyridge/southbridge.c: Create AOAC initialization code

Devices that need to have their AOAC register enabled do have a delay before
they become available. Currently each device has their own wait loop. Create
a procedure that initializes all AOAC devices in a table and wait for all
AOAC to become alive, then call this new procedure before the call to
initialize the UART. Then change all procedures that initialize some AOAC by
moving the devices to the table and removing AOAC initialization code.

TEST=Build and boot kahlee checking that UART is sending debug messages out.
