klhaung 6f496bda20 [device][platform] Update Inventec platform porting to support stretch (#2010)
* [device][platform] d6254qs d6556 platform porting
[device][platform] sensor and status led support for d7032q28b d7254q28b d7264q28b d6254qs d6556
[device][platform] qos support for d7032q28b d7254q28b
[device][platform] service configuration files for d7032q28b d7254q28b d7264q28b d6254qs d6556

* remove binary files and remove non-supported attributes in config.bcm

* remove gpio-ich here. file a PR in sonic-linux-kernel instead.

* remove unnecessary comments

* add GPL license
