clk: mediatek: Fix rate and dependency of MT8173 clocks
Remove the dependency from clk_null, and give all root clocks a typical rate, include clkph_mck_o, usb_syspll_125m and hdmitx_dig_cts. dpi_ck was removed due to no clock reference to it. Replace parent clock of infra_cpum with cpum_ck, which is an external clock and can be defined in the device tree.
