mb/google/skywalker: Add RT1019 support for beep sound

Browse source 
Derive the audio amplifier from FW_CONFIG, and set up I2C and I2S for
RT1019.RT1019 and RT9123 use the same GPIOs on the Skywalker reference
design, so the same function is used to improve code reusability. Also
pass the corresponding GPIO to the payload.

BUG=b:417083722
BRANCH=none
TEST=Build pass and test with Depthcharge change:
https://chromium-review.googlesource.com/c/chromiumos/platform/depthcharge/+/6437675
Check audio cmd in depthcharge with:
firmware-shell: AUDIO CMD=audio 500 100 1
