====================
Add driver for 1Gbe network chips from MUCSE

This patch series adds support for MUCSE RNPGBE 1Gbps PCIe Ethernet controllers
(N500/N210 series), including build infrastructure, hardware initialization,
mailbox (MBX) communication with firmware, and basic netdev registration
(Can show mac witch is got from firmware, and tx/rx will be added later).

Series breakdown (5 patches):
 01/05: net: ethernet/mucse: Add build support for rnpgbe
       - Kconfig/Makefile for MUCSE vendor, basic PCI probe (no netdev)
 02/05: net: ethernet/mucse: Add N500/N210 chip support
       - netdev allocation, BAR mapping
 03/05: net: ethernet/mucse: Add basic MBX ops for PF-FW communication
       - base read/write, write with poll ack, poll and read data
 04/05: net: ethernet/mucse: Add FW commands (sync, reset, MAC query)
       - FW sync retry logic, MAC address retrieval, reset hw with
         base mbx ops in patch4
