Add Panther Point to the list of gpio controllers

Browse Source 
The nm10 gpio driver is being modified to recognize the Panther Point
LPC device as one of valid GPIO controllers.

BUG=chrome-os-partner:8612
TEST=manual
 . build the new kernel
 . observe that the gpio driver gets installed:
    localhost ~ # dmesg | grep gpio
    [    7.020200] nm10_gpio version 0.04 built on Mar 22 2012 at 20:47:08
    [    7.020220] gpiochip_find_base: found new base at 160
 . enable the write protect GPIO (#57)
    localhost ~ # echo 217 > /sys/class/gpio/export
 . examine its value
    localhost ~ # cat /sys/class/gpio/gpio217/value
    0
 . short the pins and examine the value again
   localhost ~ # cat /sys/class/gpio/gpio217/value
   1
 . observe value change when the pins status changes
