Subject: [PATCH 2/2] net: mvpp2: implement ioctl() operation for PHY ioctls

This commit implements the ->ndo_do_ioctl() operation so that the
PHY-related ioctl() calls can work from userspace, which allows
applications like mii-tool or mii-diag to do their job.

This commit applies on top of net-next, since the mvpp2 driver was
merged there.
