mb/google/drallion: 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.

BUG=b:121309055
TEST=build/boot Windows/linux on drallion, verify touchscreen functional
in OS, dump ACPI and verify only i2c devices actually present on the
board have entries in the SSDT.
