mb/google/zork: Revert Don't expose reset GPIO for touchscreen to OS

This reverts the code from  commit 728c0787f2 that removes the reset
GPIO from the touchscreen ACPI interface.

That patch exposes a bug which leads to an invalid opcode trap in the
touchscreen code.  Reverting this gets the system working again, but is
not a long-term solution.

BUG=b:162596241
TEST=System boots to login screen.
