Some of include directives in include/linux/gpio/driver.h are
unneeded because the header does not need to know the content of
struct device, irq_chip, etc.  Just declare they are structures.

On the other hand, <linux/irqhandler.h> and <linux/spinlock_types.h>
turned out to be necessary for irq_flow_handler_t and spinlock_t,
respectively.

Each driver should include what it needs without relying on what is
implicitly included from <linux/gpio/driver.h>.  This will cut down
unnecessary header parsing.
