net: cpsw: isolate cpsw_ndo_ioctl() to just the old driver

cpsw->slaves[slave_no].phy should be equal to netdev->phydev, because it
is assigned from phy_attach_direct(). The latter is indirectly called
from the two identically named cpsw_slave_open() functions, one in
cpsw.c and another in cpsw_new.c.

Thus, the driver should not need custom logic to find the PHY, the core
can find it, and phy_do_ioctl_running() achieves exactly that.

However, that is only the case for cpsw_new and for the cpsw driver in
dual EMAC mode. This is explained in more detail in the previous commit.
Thus, allow the simpler core logic to execute for cpsw_new, and move
cpsw_ndo_ioctl() to cpsw.c.
