mb/google/dedede/var/bugzzy: Increase reset_delay_ms for touch screen
Touch screen IC couldn't wake up after rebind with current 120 ms delay after reset since the HID would be activated after 200 ms from reset. This change increases the reset_delay_ms for touch device to 200 ms to wait for the touch HID to be ready.
BUG=b:204950000 BRANCH=dedede TEST=Verified that TSP IC could wake up after rebind
