drm/amdkfd: add events IOCTL set definitions
- AMDKFD_IOC_CREATE_EVENT:
Creates a new event of a specified type
- AMDKFD_IOC_DESTROY_EVENT:
Destroys an existing event
- AMDKFD_IOC_SET_EVENT:
Signal an existing event
- AMDKFD_IOC_RESET_EVENT:
Reset an existing event
- AMDKFD_IOC_WAIT_EVENTS:
Wait on event(s) until they are signaled
v2:
- Move the limit of the signal events to kfd_ioctl.h so it
can be used by userspace
v3:
- Change all bool fields in struct kfd_memory_exception_failure
to uint32_t
