Remove a use of a negative array index from fxp(4).

This fixes a warning seen when compiling amd64 GENERIC with clang 7.
Also remove the workaround added in r337324. clang 7 and gcc 4.2
generate the same code with or without the code change.

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.

Load entire EEPROM contents in device attach time and verify
whether the checksum of EEPROM is valid or not. Because driver
heavily relies on EEPROM information when it selectively enables
features/workarounds, it would be helpful to know whether driver
sees valid EEPROM.
While I'm here remove all other EEPROM accesses since the entire
EEPROM is loaded at device attach time.

Fix and implement missing parts of flow control support. This also removes
the dev.fxp.%d.noflow tunable as the same effect can now be achieved with
ifconfig(8) by setting the flowcontrol media option as desired (besides
the tunable never having a chance to actually enable flow control support
so far).

MFC r207832:
Export hardware MAC statistics through sysctl node. Previously
fxp(4) already used to extract most hardware MAC statistics but it
didn't show them. With this change, all MAC statistics counters
are exported. Because there are a couple of new counters for 82558
and 82559, enable extended MAC statistics functionality to get
these counters. Accoring to public data sheet, 82559 MAC statistics
return 24 DWORD counters(3 counters are unknown at this moment) so
increase MAC counter structure to meet the MAC statistics block size.
The completion of MAC counter dump is now checked against
FXP_STATS_DR_COMPLETE status code which is appended at the end of
status block. Previously fxp(4) ignored the status of the
FXP_SCB_COMMAND_CU_DUMPRESET command. fxp(4) does not wait for the
completion of pending command before issuing
FXP_SCB_COMMAND_CU_DUMPRESET. Instead it skips the command and try
it next time. This scheme may show better performance but there is
chance to loose updated counters after stopping controller. So make
sure to update MAC statistics in fxp_stop().
While I'm here move sysctl node creation to fxp_sysctl_node().
