====================
net: phy: Move Omega PHY entry to Cygnus PHY driver

In order to pave the way for adding some specific Omega PHY features
that may not be desirable on other products covered by the bcm7xxx PHY
driver, split the Omega PHY entry into the Cygnus PHY driver such that
the PHY drivers are reflective of product lines/business units
maintaining them within Broadcom.

No functional changes intended.
