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.
