In 1394 OHCI specification, the format of data for IT DMA is different from
the format of isochronous packet in IEEE 1394 specification, in its spd and
srcBusID fields.
This commit adds some static inline functions to serialize/deserialize the
data of IT DMA.

In 1394 OHCI specification, the format of data for AT DMA is different from
the format of asynchronous packet in IEEE 1394 specification, in its spd
and srcBusID fields.
This commit adds some static inline functions to serialize/deserialize the
data of AT DMA.

The SelfI-ID is one type of DMAs defined in 1394 OHCI specification. It is
operated by two registers, one interrupt, and has one format of buffer.
This commit adds some static inline functions to deserialize the data in
the buffer and registers. Some KUnit tests are also added to check their
reliability.
