mediatek/mt8183: update dcxo output buffer setting
DCXO consists of core that generates clock and output buffers that
provide clock to other peripheral components.
This patch mainly eliminates the extra power consumption of output buffers.
We only enable the buffer for SOC and disable unused buffers for power-saving.
Also disable useless buffer power mode to guarantee the lowest power state.
BRANCH=none
TEST=Boots correctly on Kukui.
