mb/google/poppy: Remove digitizer reset control from ACPI
Digitizer power is not controlled by SoC. Also, since the digitizer
uses I2C-HID driver in Linux kernel, the device is put into sleep
anytime system is suspended. Thus, there is no need to control the
reset gpio using ACPI power resource.
TEST=Verified that digitizer device is properly detected on boot-up
and after suspend/resume.
