firewire updates for 6.5-rc1

The updates consist of three parts; UAPI update, OHCI driver update, and
several bug fixes.

Firstly, the 1394 OHCI specification defines method to retrieve hardware
time stamps for asynchronous communication, which was previously
unavailable in user space. This change adds new events to the UAPI,
allowing applications to retrieve the time when asynchronous packet are
received and sent. The new events are tested in the breeding edge of
libhinawa and look to work well. The new version of libhinawa will be
released after current merge window is closed.

Secondly, the FireWire stack includes a PCM device driver for 1394 OHCI
hardware, This change modernizes the driver by managed resource (devres)
framework.

Lastly, the rest of change is bug fixes for firewire-net and firewire-core.
