[PATCH v2 2/2] irqchip/aspeed-scu-ic: Fix irq_of_parse_and_map() return value

[Krzysztof Kozlowski]

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

Fixes: 04f605906ff0 ("irqchip: Add Aspeed SCU interrupt controller")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski at linaro.org>
