The DMA (NHI) port of a switch provides access to the NVM of the host controller (and devices starting from Intel Alpine Ridge). The NVM contains also more complete DROM for the root switch including vendor and device identification strings. This will look for the DMA port capability for each switch and if found populates sw->dma_port. We then teach tb_drom_read() to read the DROM information from NVM if available for the root switch. The DMA port capability also supports upgrading the NVM for both host controller and devices which will be added in subsequent patches. This code is based on the work done by Amir Levy and Michael Jamet.
