accel/amdxdna: Add command doorbell and wait support
Expose the command doorbell register to userspace on a per-hardware
context basis, enabling applications to notify the firmware of pending
commands via doorbell writes.
Introduce DRM_IOCTL_AMDXDNA_WAIT_CMD to allow userspace to wait for
completion of individual commands.
