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.
