dp83640: Ensure against premature access to PHY registers after reset

[ Upstream commit 76327a35caabd1a932e83d6a42b967aa08584e5d ]

The datasheet specifies a 3uS pause after performing a software
reset. The default implementation of genphy_soft_reset() does not
provide this, so implement soft_reset with the needed pause.
