Add support for the Qualcomm IPQ50xx in the QCA NSS dataplane driver. The QCA implementation uses old DMA api calls and a downstream SCM call, so convert to proper Linux DMA and SCM api calls. In addition, add fixed-link support to support SGMII which is used to connect the internal IPQ50xx switch to an external switch (such as QCA8337) Co-developed-by: Ziyang Huang <hzyitc@outlook.com> Signed-off-by: Ziyang Huang <hzyitc@outlook.com> Signed-off-by:George Moussalem <george.moussalem@outlook.com>
