Doug Berger 8064a711c4 net: bcmgenet: synchronize UMAC_CMD access 
commit 0d5e2a8223 upstream

The UMAC_CMD register is written from different execution
contexts and has insufficient synchronization protections to
prevent possible corruption. Of particular concern are the
acceses from the phy_device delayed work context used by the
adjust_link call and the BH context that may be used by the
ndo_set_rx_mode call.

A spinlock is added to the driver to protect contended register
accesses (i.e. reg_lock) and it is used to synchronize accesses
to UMAC_CMD.

Fixes: 1c1008c793 ("net: bcmgenet: add main driver file")
