[Netberg][Barefoot] Added support for Aurora 610 (#10579) Why I did it Support Intel Tofino based platforms Netberg Aurora 610 ASIC: Intel Tofino BFN-T10-032D-020 Pors: 48x 25G + 8x 100G How I did it Added specification to device/netberg directory Added platform/barefoot/sonic-platform-modules-netberg contains kernel modules, scripts and sonic_platform packages. Modified the platform/barefoot/one-image.mk and platform/barefoot/rule.mk to include Aurora 610 related ID and files. How to verify it Build SONiC Install the image on the device and verify the related components are installed and shown correctly.

* low order byte. The laser wavelength is equal to the 16-bit integer value
* divided by 20 in nm (units of 0.05 nm). This resolution should be adequate
* to cover all relevant wavelengths yet provide enough resolution for all
* expected DWDM applications. For accurate representation of controlled
* wavelength applications, this value should represent the center of the
* guaranteed wavelength range.
* If the free side device is identified as copper cable these registers will
* be used to define the cable attenuation. An indication of 0 dB attenuation
* refers to the case where the attenuation is not known or is unavailable.
* Byte 186 (00-FFh) is the copper cable attenuation at 2.5 GHz in units of 1 dB.
* Byte 187 (00-FFh) is the copper cable attenuation at 5.0 GHz in units of 1 dB.
