[PATCH] pci: altera: remove unused 'node' variable

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

This variable is only used when CONFIG_OF is enabled:

drivers/pci/controller/pcie-altera.c: In function 'altera_pcie_init_irq_domain':
drivers/pci/controller/pcie-altera.c:855:29: error: unused variable 'node' [-Werror=unused-variable]
  855 |         struct device_node *node = dev->of_node;

Use dev_fwnode() in place of of_node_to_fwnode() to avoid this.

----
I checked the other PCI host bridge drivers as well, this is the
only one with that problem.

Fixes: bbc94e6f72f2 ("PCI: Switch to irq_domain_create_linear()")
