Xu Yilun d43f20bae5 fpga: dfl: fme: add interrupt support for global error reporting 
Error reporting interrupt is very useful to notify users that some
errors are detected by the hardware. Once users are notified, they
could query hardware logged error states, no need to continuously
poll on these states.

This patch adds interrupt support for fme global error reporting sub
feature. It follows the common DFL interrupt notification and handling
mechanism. And it implements two ioctls below for user to query
number of irqs supported, and set/unset interrupt triggers.

 Ioctls:
 * DFL_FPGA_FME_ERR_GET_IRQ_NUM
   get the number of irqs, which is used to determine whether/how many
   interrupts fme error reporting feature supports.

 * DFL_FPGA_FME_ERR_SET_IRQ
   set/unset given eventfds as fme error reporting interrupt triggers.
