mb/google/octopus: Use runtime detection for touchscreens/digitizers
Switch from using ACPI "probed" flag to "detect" flag for all i2c
touchscreens and digitizers. This removes non-present devices from the
SSDT and relieves the OS of the burden of probing.
Test: build/boot Windows/Linux on various octopus variants, verify
touchscreens/digitizers functional, dump ACPI tables and verify only i2c
devices actually present on the board have entries in the SSDT.
