intel/i210: Set bus master bit in command register
There are still Ethernet drivers out there in the wild which expect that the master enable bit was set by firmware. A missing master enable bit will lead to a non-functional driver. Though it is clear the task of the driver to set this bit it is too late now. So work around this issue on firmware level...again!
