H3's CCU includes some switches which disable non-secure access to some of the more critical clock controls, such as MBUS, PLLs, and main platform busses. Configure them to enable non-secure access. For now the only SoC that has this feature is the H3. For other platforms just use a default (weak) empty function so things do not break.
