[PATCH] thermal/samsung: Use platform_get_irq() in exynos_tmu

[Rosen Penev]

Replace deprecated irq_of_parse_and_map() with platform_get_irq() for IRQ
retrieval in exynos_tmu, and change error handling to propagate the error
code directly. This improves maintainability and aligns with standard
driver practices. irq_of_parse_and_map() requires irq_dispose_mapping(),
which is missing.
