[PATCH v1 2/5] stmmac: intel: Remove unnecessary loop for PCI BARs

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Copy'n'paste without thinking is not a good idea and in this case it brought
unnecessary loop over PCI BAR resources which was needed to workaround one of
STMicro RVP boards. Remove unnecessary loops from Intel driver.
