mb/google/guybrush/var/guybrush: Add GPIO override table

EN_SPKR is routed to SD pin in the ALC1019 speaker amplifier. The
concerned pin has a voltage rating of 1.8V whereas the EN_SPKR GPIO has
a voltage rating of 3.3 V. The schematics has been updated to bridge the
gap. So enable the speaker amplifier by default and add a gpio override
table to disable the speakers before board version 2.

Also update the codec ACPI HID name for the kernel machine driver to
probe the codec successfully.

BUG=b:182960979
TEST=Build and boot to OS in guybrush. Ensure that the GPIO output state
is high.
