soc/mediatek/mt8196: Add clk_buf drivers

MT8196 use MT6685 clk_buf, and will use new RC mode with srclken_rc.
The clk_buf will provide several 26M clocks, and these clocks can be
independently turned on. RC mode will determine which clocks to be
turned on based on users' requests, which is collected into PMRC_EN
register by srclken_rc.

TEST=Build pass.
