[net-next,v2, 1/3] net: stmmac: create dwmac-intel.c to contain all Intel platform
From: Voon Weifeng
Date: Mon Mar 30 2020 - 13:05:21 EST
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.
