presence:ibm,bonnell: Add config file
The Bonnell system has 2 dual rotor fans with their presence detect
GPIOs wired directly to the BMC using GPIOs F4 and F5. The device tree
has these configured as GPIO keys 6 and 7.
The 'physpath' values are only used by the 'Fallback' presence
redundancy policy, which we are not using because we're using 'AnyOf'
instead. On other systems that would be the I2C device path of the IO
expander the presence detects are wired to. In this case they're wired
to the BMC so an I2C path doesn't apply, so I just chose 'BMC' to have
something there, which again isn't used anyway but the code requires
it.
