[PATCH v1 3/3] PCI: j721e: Use inline reset GPIO assignment and drop local variable

[Anand Moon]

Change removes the unnecessary local gpiod variable and assigns the result
of the devm_gpiod_get_optional() call directly to pcie->reset_gpio.
This makes the code more concise and readable without changing the
behavior.
