libgpiod_pin_1_x.py does not detect internal pulldowns

[nolanwinter]

Board Name

NanoPi Neo

Steps

1. Update the board to use the newest version of Blink.
2. Create a digitalio input pin with a pull (pin.switch_to_input(Pull.DOWN)
3. NotImplementedError is thrown.
4. Downgrade blinka to version 8.23.0 (for example)
5. Create a digitalio input pin with a pull (pin.switch_to_input(Pull.DOWN)
6. No error is thrown.

Description

On the current version of blinka (presumably any version after commit 7e23a36), the ability to use the internal pulldown resistors in the NanoPi Neo is prevented by a NotImplementedError, yet it still works with the old version of Blinka so the error is getting thrown accidently.

Thanks. It was split because it seems to only work on 1 of 3 different version ranges at a time. Pullups probably just need to be added to the version 1.x handler.
