universal. (1) New struct intr_map_data is defined as a container for arbitrary description of an interrupt used by a device. Typically, an interrupt number and configuration relevant to an interrupt controller is encoded in such description. However, any additional information may be encoded too like a set of cpus on which an interrupt should be enabled or vendor specific data needed for setup of an interrupt in controller. The struct intr_map_data itself is meant to be opaque for INTRNG. (2) An intr_map_irq() function is created which takes an interrupt controller identification and struct intr_map_data as arguments and returns global interrupt number which identifies an interrupt. (3) A set of functions to be used by bus drivers is created as well as a corresponding set of methods for interrupt controller drivers. These sets take both struct resource and struct intr_map_data as one of the arguments. There is a goal to keep struct intr_map_data in struct resource, however, this way a final solution is not limited to that. (4) Other small changes are done to reflect new situation. This is only first step aiming to create stable interface for interrupt controller drivers. Thus, some temporary solution is taken. Interrupt descriptions for devices are stored in INTRNG and two specific mapping function are created to be temporary used by bus drivers. That's why the struct intr_map_data is not opaque for INTRNG now. This temporary solution will be replaced by final one in next step. Differential Revision: https://reviews.freebsd.org/D5730
