Blackbird requires additional firmware work to enable 2666MHz DIMMs.

While some specific DIMMs work, we prefer to reduce user confusion
at this juncture and at least allow user systems to IPL pending
the requisite firmware update.

Reduce DIMM slots to the two slots present on Blackbird

Work around phosphor-ipmi-fru-properties-mrw-native gen_fru_properties.pl creating invalid YAML files when TPM node is not found in MRW

Backport of romulus-xml commit 7f925b710c483ffefe84756c3e7ffb225df24793

Add 2666 to supported speed and change single drop definitions to use 2666.

Backport of romulus-xml commit 97b82bfd90db00df820e53c0192086376048fcec

This reverts commit 52fc6123.
Stop states should now be ready for testing

Update MAX_ALLOWED_DIMM_FREQ to allow 2666MHz DIMM modules to run at full speed when in a single drop configuration.

Change tested with 4x M393A2K40BB2-CTD modules.

This works around system instability on DD2.1 / DD2.2 with currently IPLing hostboot versions

Add OCuLink port definitions

Copying WOF attributes from witherspoon/zaius

Remove fan connector #7 from Talos MRW pending proper phosphor-hwmon integration for the BMC PWM/tach

Remove FSI_LINK attribute from fsim-X global settings

  - This was overriding the intended MRW values with an
    empty string which eventually resulted in incorrectly
    processed FSI data on the slave proc
