/**
* @brief platform_register_metal_device() - Statically Register libmetal
* devices.
* This function registers the IPI, shared memory and
* TTC devices to the libmetal generic bus.
* Libmetal uses bus structure to group the devices. Before you can
* access the device with libmetal device operation, you will need to
* register the device to a libmetal supported bus.
* For non-Linux system, libmetal only supports "generic" bus, which is
* used to manage the memory mapped devices.
*
* @return 0 - succeeded, non-zero for failures.
