sunxi: Support H3 CCU security switches
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.
