Driver for the PCA9641 2-channel I2C bus master arbiter chip.
It's a pretty sweet little chip that lets you connect two i2c mastering devices
to a shared downstream bus and makes sure that only one master can address the
downstream devices at a time. It can also relay downstream interrupts to the
mastering devices.
