net: dsa: mv88e6xxx: Workaround missing PHY ID on mv88e6390
The internal PHYs of the mv88e6390 do not have a model ID. Trap any calls to the ID register, and if it is zero, return the ID for the mv88e6390. The Marvell PHY driver can then bind to this ID.

However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0 and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set. The fix is to make the tryget routines use an actual boolean internally instead of the atomic long result truncated to a int.
