* Bump sonic-platform-modules-arista
Improves i2c performance for xcvrs
Fix the led_plugin by ignoring unknown ports
Miscellaneous improvements
* Fix index column for Arista-7260CX3-D108C8
* Fix flash permissions for Arista platforms
The ext4 flash uses acl to properly handle permissions in EOS.
Aboot isn't built with this support and therefore can't be used
to set the flash permissions. It has to be deferred in sonic initrd.
* [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)
