Using the of_fwnode_handle() means that local 'node' variables are unused
whenever CONFIG_OF is disabled for compile testing:

drivers/mfd/88pm860x-core.c: In function 'device_irq_init':
drivers/mfd/88pm860x-core.c:576:29: error: unused variable 'node' [-Werror=unused-variable]
  576 |         struct device_node *node = i2c->dev.of_node;
      |                             ^~~~
drivers/mfd/max8925-core.c: In function 'max8925_irq_init':
drivers/mfd/max8925-core.c:659:29: error: unused variable 'node' [-Werror=unused-variable]
  659 |         struct device_node *node = chip->dev->of_node;
      |                             ^~~~
drivers/mfd/twl4030-irq.c: In function 'twl4030_init_irq':
drivers/mfd/twl4030-irq.c:679:46: error: unused variable 'node' [-Werror=unused-variable]
  679 |         struct                  device_node *node = dev->of_node;
      |                                              ^~~~

Replace these with the corresponding dev_fwnode() lookups that
keep the code simpler in addition to avoiding the warnings.

Thomas, can you pick this up into the tip/irq/cleanups branch that
contains the earlier commit that introduced the warnings?
