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.
