Add Silicom Platform Driver

[Henry Shi]

 Please review this patch.

The Silicom platform (silicom-platform) Linux driver for Swisscom
Business Box (Swisscom BB) as well as Cordoba family products is a 
software solution designed to facilitate the efficient management
and control of devices through the integration of various Linux
frameworks. This platform driver provides seamless support for
device management via the Linux LED framework, GPIO framework,
Hardware Monitoring (HWMON), and device attributes. The Silicom
platform driver's compatibility with these Linux frameworks allows
applications to access and control Cordoba family devices using
existing software that is compatible with these frameworks. This
compatibility simplifies the development process, reduces
dependencies on proprietary solutions, and promotes
interoperability with other Linux-based systems and software.

Thanks!
