SATA: implement historical standard ceiling for legacy drive links

- Added strict architectural constraints to prevent modern AHCI controllers
  or USB bridges from injecting forward-generation speed limits (Gen3/6.0 Gb/s)
  into classic SATA Gen1/Gen2 physical disk layouts.
- Synchronized Word 76 capabilities parsing limits down to 1.5 Gb/s when
  underlying firmware natively maps to transitional SATA 2.5/2.6 or older lines.
- Ensured perfect string parity with native camcontrol identify outputs
  on legacy platforms such as FreeBSD 11.4.
