[PATCH 1/2] thermal/drivers/rcar_gen3: Handle -ENXIO from optional IRQ lookup

[phucduc.bui at gmail.com]

From: bui duc phuc <phucduc.bui at gmail.com>

platform_get_irq_optional() returns -ENXIO when the optional IRQ is not
specified. Treat -ENXIO as a valid absence of an optional IRQ, while
propagating other errors.
