[PATCH v2 2/2] pinctrl: nuvoton: Fix irq_of_parse_and_map() return value

[Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>]

The irq_of_parse_and_map() returns 0 on failure, not a negative ERRNO.

Fixes: 3b588e43ee5c ("pinctrl: nuvoton: add NPCM7xx pinctrl and GPIO driver")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

1. Correct the return value passed further.
