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