isa: introduce wrapper isa_connect_gpio_out

Currently a direct access to the device structure field is used to connect ISA device IRQ to the bus. GPIO access should be used instead if possible. The patch adds wrapper isa_connect_gpio_out. The function connects specified output GPIO to specified ISA IRQ. Signed-off-by: Efimov Vasily <real@ispras.ru> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
