ARM: clps711x: serial driver hungs are a result of call disable_irq within ISR

commit 7a6fbc9a887193a1e9f8658703881c528040afbc upstream.

Since 2.6.30-rc1 clps711x serial driver hungs system. This is a result
of call disable_irq from ISR. synchronize_irq waits for end of interrupt
and goes to infinite loop. This patch fix this problem.
