Subject: [PATCH 06/16] drm/amd/display: Remove ImmediateFlipSupportedSurface VBA variable

The ImmediateFlipSupportedSurface variable from the struct
vba_vars_st is only used on assignments, so its value is not used
on code. So, remove the ImmediateFlipSupportedSurface entry from the struct
vba_vars_st.
