This implements the daisy chain feature of the low side switch
BD8LB600FS. The daisy chaining is in hardware achieved via
connecting the MISO and MOSI lines of multiple instances of the IC
in a row. It is implemented in the driver through a variable number
of GPIOs on one instance. Therefore, one device tree instance of the
IC will handle multiple daisy chained physical instances.

Only provide implementations for optional operations if needed. This
patch deletes quite a few dummy `pin_interrupt_configure` ops (now
optional), and adjusts ifdeffery on some drivers so that optional ops
are only provided if they implement real functionality.
