smsc911x: Add spinlocks around registers access
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.
