Subject: [PATCH 07/16] drm/amd/display: Remove WritebackAllowFCLKChangeEndPosition VBA variable

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