firewire: ohci: add static inline functions to serialize/deserialize data of AT DMA

Browse source

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.
