Subject: [PATCH v2 1/1] spi: ppc4xx: Avoid returning 0 when failed to parse and map IRQ
0 is incorrect error code when failed to parse and map IRQ.
Replace OF specific old API for IRQ retrieval with a generic
one to fix this issue.
Fixes: 0f245463b01e ("spi: ppc4xx: handle irq_of_parse_and_map() errors")
