[PATCH v2 1/2] ethdev: decode newer SFF compliance codes

[Roman Khromenok]

Decode the compliance codes added by SFF-8472 Rev 12.5a and
SFF-8636 Rev 2.12, as ethtool does since its commits
057c4fdd85b5 ("sfpid: add support for newer SFF-8472 compliance codes")
and 75d62323302b ("qsfp: add support for newer SFF-8636 compliance codes"):

- SFF-8472 byte 10: Fibre Channel 1600 and 3200 MBytes/s.
- SFF-8636 byte 133: SAS 24.0G, and SAS 12.0G which was defined
  but not reported.
- SFF-8636 byte 138: Fibre Channel 3200 MBytes/s.

Also decode the SFF-8472 Fibre Channel Speed 2 byte 62, which byte 10
bit 1 refers to: 64GFC, reported as 6400 MBytes/s like the other
Fibre Channel speeds. ethtool does not decode it.

v2:
- report 64GFC as "FC: 6400 MBytes/sec", like the other
  Fibre Channel speeds
- refer to the ethtool commits with 12 character hashes
  and their subjects
- 2/2: set one bit at a time in the tests and check that
  the other code of the same byte is absent

Checked against SFF-8472 Rev 12.5a (Table 5-3) and SFF-8636
Rev 2.12 (Table 6-17). Based on next-net/for-main.
