[PATCH] pinctrl: samsung: exynos: replace irq_of_parse_and_map with modern APIs

[Rosen Penev <rosenp@gmail.com>]

Replace irq_of_parse_and_map() with fwnode_irq_get() for per-pin IRQ
lookup and of_irq_get() for the muxed EINT IRQ. The fwnode-based API
works with both OF and ACPI fwnodes and follows modern conventions.

For the muxed EINT path, change the error handling to propagate the
error code rather than silently returning 0.
