sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Replace all calls to minor() with dev2unit().

After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

Allow to access phy registers via ioctl().

Change device name notation.
- /dev/fw{,mem}X.Y represents the Y'th unit on the X'th bus.
- /dev/fw{,mem}X is an alias of fw{,mem}X.0 for compatibility.
- Clone devices.

Clean up fwdev.

Allocate iso DMA channel dynamically. This allows us to have more

Many internal structure changes for the FireWire driver.

- Compute CRC in CROM parsing.
- Add support for configuration ROM build.
- Simplify dummy buffer handling.
- busdma conversion
- Use swi_taskqueue_giant for -current. Mark the interrupt routine as MPSAFE.
- AR buffer handling.
Don't reallocate AR buffer but just recycle it.
Don't malloc and copy per packet in fwohci_arcv().
Pass packet to fw_rcv() using iovec.
Application must prepare receiving buffer in advance.
- Change fw_bind API so that application should pre-allocate xfer structure.
- Add fw_xfer_unload() for recycling struct fw_xfer.
- Add post_busreset hook
- Remove unused 'sub' and 'act_type' in struct fw_xfer.
- Remove npacket from struct fw_bulkxfer.
- Don't call back handlers in fwochi_arcv() if the packet has
not drained in AT queue
- Make firewire works on big endian platform.
- Use native endian for packet header and remove unnecessary ntohX/htonX.
- Remove FWXFERQ_PACKET mode. We don't use it anymore.
- Remove unnecessary restriction of FWSTMAXCHUNK.
- Don't set root node for phy config packet if the root node is
not cycle master capable but set myself for root node.
We should be the root node after next bus reset.
