mb/google/kukui: help payload to identify correct speaker amp type 

Kukui based devices may use different speaker amplifiers, for example
MAX98357A, RT1015, or RT1015Q/automode. To help payloads identifying
which component was installed on board, we want to pass the speaker GPIO
in different name. This can be set in Kconfig as CONFIG_SPEAKER_GPIO_NAME.
