arm64: dts: qcom: sc7180: Fully describe fingerprint node on Trogdor

Browse Source 
Update the fingerprint node on Trogdor to match the fingerprint DT
binding. This will allow us to drive the reset and boot gpios from the
driver when it is re-attached after flashing. We'll also be able to boot
the fingerprint processor if the BIOS isn't doing it for us.
