- open-source CAR setup
- NCT6687D serial port with TX pin exposed on JBD1 header
- SMBus reading SPD from all 4 DIMMs

There is a requirement that the TPM RST signal cannot be asserted by
software. On nissa this is PLT_RST_L, so lock this pin to prevent it
being reconfigured as a GPIO.
BUG=b:216671701
TEST=Try to change GPP_B13 from the kernel:
$ echo 677 > /sys/class/gpio/export
$ echo out > /sys/class/gpio/gpio677/direction
$ echo 0 > /sys/class/gpio/gpio677/value
$ echo 1 > /sys/class/gpio/gpio677/value
GSC console doesn't show "PLT_RST_L ASSERTED" / "PLT_RST_L DEASSERTED"
