Yury Georgievskiy 0ac8382e9c serial: mcf: don't take spinlocks in already protected functions 
Don't take the port spinlock in uart functions where the serial core
already takes care of locking/unlocking them.

The code would actually lock up on architectures where spinlocks are
implemented.

Also protect calling mcf_rx_chars/mcf_tx_chars in the interrupt handler by
the port spinlock and use IRQ_RETVAL to return from isr.

[akpm@linux-foundation.org: make irq-handler return value more explicit]
