smsc911x: Add spinlocks around registers access
commit 492c5d943d6a04b124ba3a719dc746dc36b14cfb upstream.
On SMP systems, the SMSC911x registers may be accessed by multiple CPUs
and this seems to put the chip in an inconsistent state. The patch adds
spinlocks to the smsc911x_reg_read, smsc911x_reg_write,
smsc911x_rx_readfifo and smsc911x_tx_writefifo functions.
