[PATCH v2 13/17] net: phy: Check phy_mask in get_phy_device()

[Andrey Smirnov <andrew.smirnov@gmail.com>]

Do not try to probe PHY devices if they are masked via phy_mask of the
corresponding bus. This way we won't try adding devices that are
unlikely to be proper PHYs by default. With this change it is still
remain to be possible to add such a device to the bus explicitly
either using "miitool" or calling phy_device_create() explicilty.
