clk: mediatek: add MUX_GATE_FLAGS_2
Add MUX_GATE_FLAGS_2 for the clock which needs to set two falgs. Such as some mux need to set the flags of "CLK_MUX_ROUND_CLOSEST". Signed-off-by: chunhui dai <chunhui.dai@mediatek.com> Signed-off-by: wangyan wang <wangyan.wang@mediatek.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
