Commit Message:
BACKENDS: SDL: Use 22050 Hz output rate on Atari

Commit 387ceddef1d picked the Falcon rate closest to 44100 Hz. Request
22050 Hz instead to a) be less CPU-heavy b) give the FireBee, Falcon +
external DSP clock and other XBIOS backends chance to use a frequency
native to most of the games.

If there 22050 Hz is not supported, it will offer the nearest one
available, same as Atari mixer does.
