cirrus/mac89x0: print MAC via printk format specifier
Print MAC/dev_addr via printk extended format specifier %pM instead of custom code. Use memcpy to set the address to dev->dev_addr in set_mac_address, instead of mxing it up in a for loop with printing a debug msg. Check also if the given address is valid.
