igc: Change Device Reset to Port Reset
The _reset_hw_base method switched from port reset (CTRL[26]) to device
reset (CTRL[29]) since the FW was receiving an interrupt on CTRL[29].
FW code was later modified to also receive an interrupt on CTRL[26].
Since certain HW values are not reset to default by CTRL[29], we go back
to CTRL[26] for the HW reset, as it meets all current requirements.
This reverts commit bb4265ec24c1 ("igc: Update the MAC reset flow").
