net: stmmac: create dwmac-intel.c to contain all Intel platform

As stmmac_pci.c file is getting bigger and more complex, it is reasonable to separate all the Intel specific dwmac pci device to a different file. This move includes Intel Quark, TGL and EHL. A new kernel config CONFIG_DWMAC_INTEL is introduced and depends on X86. For this initial patch, all the necessary function such as probe() and exit() are identical besides the function name.
