palkia: separate the gpio pins control for the second touch

There are two touch screen controllers on the Palkia device.
One is on the lid; another is on the base. To support
the different control path (for example: turning off the base's
touch event when we don't want to use it however still keeping
the lid's touch event), we use the different gpio pins to control
the second touch. As a result, we need to modify the devicetree
to adopt this change. With this change, we can control the
primary and secondary touch screen controller respectively.

BUG=b:149714955
TEST=lid/base touch screen works correctly
