Allocate doorbells for dGPUs in the SVM aperture and map them for
GPU access. This is necessary to allow GPU-initiated submissions to
user mode queues.
Depends on new doorbell BO allocation flag in KFD.

[ROCm/ROCR-Runtime commit: 2e0a6eb371]
KFD may not be able to provide the precise VM fault address and status.
This flag will indicate whether the event data has the fault details

[ROCm/ROCR-Runtime commit: 79077811f5]
Allocate SVM address space for the registered memory and use new
userptr support in KFD to create a system memory BO associated with
the given user pointer. Map this BO at the SVM address for CPU
access.
MapMemoryToGPU can be used with the registered user pointer and
will return the SVM address as alternate GPUVA.

1. Add IOCTL defines to set trap handler
2. Add control stack size information on create queue argument.
3. Increase the total save&restore area size for carrizo to include the control stack size.
