phy: ti: j721e-wiz: Invoke wiz_init() before of_platform_device_create()
Invoke wiz_init() before configuring anything else in Sierra/Torrent
(invoked as part of of_platform_device_create()). wiz_init() resets the
SERDES device and any configuration done in the probe() of
Sierra/Torrent will be lost. In order to prevent SERDES configuration
from getting reset, invoke wiz_init() immediately before invoking
of_platform_device_create().
