mb/google/guybrush/var/guybrush: Reconfigure left speaker amplifier
In order to resolve the I2C address conflict with another peripheral in
the upcoming hardware build, left speaker amplifier I2C address is
reconfigured.
BUG=b:188539052
TEST=Build Guybrush mainboard. On Guybrush board ID 1, all the 3
speaker amplifiers are added to the ACPI table.
\_SB.I2C2.D028: Realtek SPK AMP L at I2C: 03:28
\_SB.I2C2.D029: Realtek SPK AMP R at I2C: 03:29
\_SB.I2C2.D02A: Realtek SPK AMP L1 at I2C: 03:2a
At the OS side, the concerned speaker amplifiers are probed and
enumerated.
