[PATCH v2 05/10] of/irq: Introduce __irq_of_parse_and_map()

This is a version of irq_of_parse_and_map() that propagates the precise error code instead of returning 0 for all errors. It will be used in subsequent patches to allow further propagation of error codes. To avoid code duplication, implement irq_of_parse_and_map() as a static inline wrapper
