4963049ea1 drm/hyperv: Replace simple-KMS with regular atomic helpers
Drop simple-KMS in favor of regular atomic helpers to make the code more
modular. The simple-KMS helper mix up plane and CRTC state, so it is
obsolete and should go away [1]. Since it just split the simple-pipe
functions into per-plane and per-CRTC, no functional changes is
expected.

b253c3026c drm/hyperv: Fix double mouse pointers
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.
