net: ethernet: sunplus: Switch to ndo_eth_ioctl

The device ioctl handler no longer calls ndo_do_ioctl, but calls
ndo_eth_ioctl to handle mii ioctls since commit a760537
("dev_ioctl: split out ndo_eth_ioctl"). However, sunplus still used
ndo_do_ioctl when it was introduced. So switch to ndo_eth_ioctl.

Bad commit fd3040b ("net: ethernet: Add driver for Sunplus SP7021")
was the initial driver commit, meaning that PHY IOCTLs where never
available on this driver. Therefore don't consider this as a fix.

Found by code inspection.
