Subject: [PATCH net-next 2/2] net: fixed_phy: set is_gigabit_capable member when needed

The fixed_phy driver does not set the phydev->is_gigabit_capable member
when the fixed_phy is gigabit capable. This in turn causes
phy_device.c:genphy_read_status function to return unknown phy
parameters (SPEED_UNKNOWN, DUPLEX_UNKNOWN, ...), if the fixed_phy is
created with SPEED_1000.
