mb/google/var/fatcat/lapis: set custom SVID/SSID to load fw for CS35L56

The Lapis board has a Cirrus CS35L56 smart audio amplifier, which needs
board-specific firmware to work properly [1]. The OS uses the SVID/SSID
of the host PCI audio interface to know which firmware file to use.

Set the correct SVID/SSID for Lapis so that the OS can load the correct
firmware for the CS35L56.
