Split the RC related routines into pcie-mobiveil-host.c, and common routines into pcie-mobiveil.c, move the macro definitions and function declarations into pcie-mobiveil.h, and the Mobiveil platform reference code into pcie-mobiveil-plat.c. So that it is easy to reuse the extracted routines to add a new host driver, which integrated Mobiveil PCIe GPEX IP.
