[PATCH net-next] of: mdio: preserve phy dev_flags in of_phy_connect()

[rentao.bupt at gmail.com]

From: Tao Ren <rentao.bupt at gmail.com>

Replace assignment "=" with OR "|=" for "phy->dev_flags" so "dev_flags"
configured in phy probe() function can be preserved.

The idea is similar to commit e7312efbd5de ("net: phy: modify assignment
to OR for dev_flags in phy_attach_direct").
