mb/google/skyrim: Use detect vs probed flag for touchscreens 

Now that coreboot performs the necessary power sequencing, switch
from using the 'probed' flag to 'detect' for all I2C touchscreens.
This alleviates ChromeOS from having to probe to see which
touchscreen model is actually present, prevents breaking ACPI spec
by generating device entries with status 'enabled and present'
which aren't actually present, and improves compatibility with
upstream Linux and Windows.

BUG=b:121309055
TEST=build/boot ChromeOS and Linux on skyrim, ensure touchscreen is
functional, and ACPI device entry generated for correct touchscreen
model.
