[PATCH v2 1/2] arm64: dts: qcom: Fully describe fingerprint node on Herobrine

[Stephen Boyd]

Update the fingerprint node on Herobrine 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.
