broadcom: Remove SoC and board support

The reason for this code cleanup is the legacy
Google Purin board which isn't available anymore
and AFAIK never made it into the stores.

* Remove broadcom cygnus SoC support
* Remove /util/broadcom tool
* Remove Google Purin mainboard
* Remove MAINTAINERS entries
