Instead of distingting between shared and exclusive fences specify

Rework all drivers to use this interface instead and deprecate the old one.
This patch broke compilation for the vc4 DRM driver.
My apologies for that. I've tried really hard to catch all cases, but
looks like I missed some.
I've this patch locally
which seems to work but I don't know enough about the fence API to know if
is correct.
If you think is the proper fix then I can post it as a patch.
Yes, that patch looks absolutely correct to me.
Feel free to add an Reviewed-by: Christian König
<christian.koenig@xxxxxxx> and CC me so that I can push it to
drm-misc-next ASAP.
Thanks,
Christian.

Subject: [PATCH] drm/vc4: Use newer fence API to fix build error
The commit 73511edf8b19 ("dma-buf: specify usage while adding fences to
dma_resv obj v7") ported all the DRM drivers to use the newer fence API
that specifies the usage with the enum dma_resv_usage rather than doing
an explicit shared / exclusive distinction.
But the commit didn't do it properly in two callers of the vc4 driver,
leading to build errors.
Fixes: 73511edf8b19 ("dma-buf: specify usage while adding fences to dma_resv obj v7")
