Subject: drm/amd/display: check for ipp before calling cursor operations
Git-commit: d6b6669762898dfc99e9273b8d8603bc47014aa9
Patch-mainline: v4.16-rc4
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Currently all cursor related functions are made to all
pipes that are attached to a particular stream.
This is not applicable to pipes that do not have cursor plane
initialised like underlay.
Hence this patch allows cursor related operations on a pipe
only if ipp in available on that particular pipe.
The check is added to set_cursor_position & set_cursor_attribute.
