Introducing new register and unregister API for ifpga interrupt. 1. register FME and AFU interrupt ifpga_register_msix_irq() 2. unregister FME and AFU interrupt ifpga_unregister_msix_irq() On PAC N3000 card, there is one PCIe MSIX interrupt for FME management, like the error report, thermal management, we use this interrupt in ifpga_rawdev device driver. on the other hand, there are about 4 PCIe MSIX interrupts are reserved for AFU which end-user can use those interrupts in their AFU logic design. End-user can use those APIs to register interrupt handler in their AFU drivers. Signed-off-by: Tianfei Zhang <tianfei.zhang@intel.com> Signed-off-by: Andy Pei <andy.pei@intel.com>
