Hou Zhiqiang 03bdc38840 PCI: mobiveil: Modularize the Mobiveil PCIe Host Bridge IP driver
Modularize the Mobiveil PCIe host driver according to the abstraction of
Root Complex and Endpoint and move it into a new directory in order to
make it easier to reuse the driver functions to add new host drivers for
systems integrating the Mobiveil PCIe GPEX IP.
