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!
