mb/google/variant/nocturne: set CONFIG_NO_FADT_8042
Set CONFIG_NO_FADT_8042 to avoid probing for the 8042 controller.
This speeds up boot on nocturne by 1.3 seconds:
Before change:
[2.162266] EXT4-fs (mmcblk0p3): mounting ext2 file system using
the ext4 subsystem
After change:
[0.867735] EXT4-fs (mmcblk0p3): mounting ext2 file system using
the ext4 subsystem
BUG=b:120960844
BRANCH=none
TEST=build, flash, and boot nocturne; check dmesg to verify that
boot is faster and that you don't see the following log in dmesg:
[0.671501] i8042: Probing ports directly.
