honeybuns: override function for pd_can_source_from_device
This CL adds honeybuns policy for power role swap. Always return false
so we will request a power role swap if in a sink role and port
partner is DRP capable.
BUG=b:182441965
BRANCH=None
TEST=verfied that on quiche when attaching as a sink that a power role
swap request is generated. Previously, quiche relied on the host
requesting a power role swap.
