Subject: [PATCH] drm/hyperv: Fix double mouse pointers

It looks like Hyper-V supports a hardware cursor feature. It is not used
by Linux VM, but the Hyper-V host still draws a point as an extra mouse
pointer, which is unwanted, especially when Xorg is running.

The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted
pointer.
When the hyperv_drm driver was developed, the function
synthvid_send_ptr()
was not copied from the hyperv_fb driver. Fix the issue by adding the
function into hyperv_drm.

Fixes: 76c56a5affeb ("drm/hyperv: Add DRM driver for hyperv synthetic
video device")
