Why I did it
To enable autonegotiation/link training on some Broadcom-based platforms (Arista 7060 and 7260, Celestica DX010)
How I did it
Add appropriate SOC property for enabling the feature to the Broadcom config files of appropriate platforms
Also convert line endings to UNIX format for one Celestica file
* [test] Adding Broadcom configuration file test
In order to allow SONiC community to check in Broadcom configuration
file directly under device folder. We need to add this test to make
sure the contents of the configuration is compliant with Broadcom
specifications.
* Invoke test from Debian package builder
* Use $() syntax
* Remove the debug echo statement
