z85230: spinlock logic

At some point someone added a spin_lock(&dev->lock) to the IRQ handler for
the Z85230 driver.  This actually correctly fixes a bug but the necessary
changes to remove the chan->lock calls in the event handlers were not made
(c->lock is the same lock).

Simona Dascenzo reported the problem with the driver and this patch should
fix the problem he found.
