mb/google/guybrush/var/nipperkin: Update privacy GPIO to Graphics DRM
GPIO_18 is used for LCD_PRIVACY_SCREEN feature starting board phase 2.
But it is programmed incorrectly in the concerned ACPI device. Pass the
correct GPIO.
BUG=b:204401306
TEST=Build and boot to OS in Nipperkin. Ensure that the ACPI object
contains the right GPIO. Ensure that the screen visibility gets updated
by pressing the privacy screen button.
