crossystem: Add LynxPoint to list of valid x86 chipset types

Haswell CPUs are paired with the LynxPoint chipset and this
needs to be a valid controller name for crossystem.

BUG=chrome-os-partner:19263
BRANCH=none
TEST=manual

This was tested on a wtm2 system to ensure that a GPIO
defined in chromeos ACPI that is exported by the kernel at
/sys/devices/platform/chromeos_acpi/GPIO.# is used by crossystem
and the GPIO is exported in /sys/class/gpio and read.

$ cat /sys/devices/platform/chromeos_acpi/GPIO.1/GPIO.2
34
$ cat /sys/class/gpio/gpio196/value
1
$ crossystem wpsw_cur
1
