Looks like this makes the ap_compute test on embedded-qnx-hv
e3550-t194 quite bad. Might also affect ap_resmgr.

0601fd25a5 gpu: nvgpu: gv100: nvlink endpoint driver 
The following changes implements the initial (as per bringup) nvlink driver.

(1) SW initialization of nvlink core driver structures
(2) Nvlink interrupt handling
(3) Device initialization (IOCTRL, pll and clocks, device level intr)
(4) Falcon support for minion
(5) Minion load and bootstrapping
(6) Link initialization and DL PROD settings
(7) Device Interface init (and switching HSHUB to nvlink)
(8) HS set/get mode for both link and sublink
(9) Topology discovery and VBIOS settings.
(10) Ensures we get physical contiguous memory when Nvlink is enabled

This driver includes a hack for the current single dev/single link limitation.
