dts: revpi-core: pull down sniff pin
requested to merge github/fork/linosanfilippo-kunbus/fix/REVPI-1783/fix_pin_pull into devel/revpi-5.10
Created by: linosanfilippo-kunbus
There is no resistor to pull down sniff pin A2. This leads to a false detection of a device on the left side of the pi-bridge in case that no devices are connected: in this case a high signal level is read from the line which is interpreted as an existing device during the pi-bridge detection procedure.
Fix this by using the internal pull down of the pin controller.
