mb/google/poppy: Use runtime detection for touchscreens/digitizers
Now that power sequencing has been implemented, switch from using ACPI
"probed" flag to "detect" flag for all i2c touchscreens/digitizers.
This removes non-present devices from the SSDT and relieves the OS of
the burden of probing.
BUG=b:121309055
TEST=build/boot Windows/linux on all poppy variants, verify all
touchscreens functional in OS, dump ACPI and verify only i2c devices
actually present on the board have entries in the SSDT.
