* [202012] Add SOC property to enable AN/LT on some platforms
Why I did it
To enable autonegotiation/link training on some Broadcom-based platforms (Arista 7060CX, 7260CX3, 7050cx3, 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
* Add 'phy_an_lt_msft' to BCM config file permitted list
Set hierarchical ecmp level to 2 instead of 3. Based on CS00011833367, ecmp level must be set to 2.
This is already handled for TH2 platforms. Change is required only for TD3

Need A mmu configuration to get the device going without generating lots of warnings.
Similar to dummy MMU configuration for Arista-7050CX3-32S-C32, this configuration will need to be updated with correct numbers. This MMU configuration is copied from 7060 comparable hwsku.
