sb/lynxpoint/gpio: fix interrupt storm

On newer kernels (> 4.9 LTS), the GPIO ACPI device's interrupt
resource causes an interrupt storm which prevents the CPU
from properly idling, significantly increasing power consumption.
This was fixed for soc/broadwell (which also supports lynxpoint-lp)
by removing the interrupt resource, so apply the same fix here.

Original fix: https://chromium-review.googlesource.com/203645

Test: build/boot google/wolf, verify CPU0 idles correctly and
power consumption drop via powertop in kernels 4.16.18 and 5.x.
