Why I did it
To support dynamic port breakout Broadcom configurations on Arista platforms.
How I did it
Updated platform.json for platforms and added new hwsku, Broadcom config, and hwsku.json for dynamic port breakout usage.
The name of the new hwsku name used is very similar to the platform name (platform x86_64-arista_7050_qx32s hwsku Arista-7050QX-32S) as the flex hwsku is meant to be the default in the future.
How to verify it
Boot up device with the new hwsku, interfaces are up.
Change hwsku.json with new default breakout mode and reload device, breakout will have successfully been applied.
* [Device] Rename SKU Arista-7260CX3-64 to Arista-7260CX3-C64
Renaming to add the speed indication: C64 means 64 100G ports.
renamed: Arista-7260CX3-64/port_config.ini -> Arista-7260CX3-C64/port_config.ini
renamed: Arista-7260CX3-64/sai.profile -> Arista-7260CX3-C64/sai.profile
* [Arista-7260cx3] Fix 64x100G port_config.ini
Reorder the port lanes to match the front panel port numbering.
* [Arista-7260CX3] add hwSKU Arista-7260CX3-D108C8
This hwSKU has 108x50G ports and 8x100G ports (2 x 100G ports are unused)
