Because vid_pll_div parent is HDMI_PLL, and HDMI_PLL is a fixed
frequency. Flags is CLK_SET_RATE_PARENT. So we use RO.
Can I remove RO and use CLK_SET_RATE_NO_REPARENT instead, which one do
you think is more reasonable?

Since fclk_div* is a fixed frequency value, mplL1 and hifi_pll and
gp0_pll are used by other specialized modules, vid_pll has
CLK_SET_RATE_PARENT. The parent of vid_pll is that vid_pll_sel uses
CLK_SET_RATE_NO_REPARENT.

[16:12] is gen_clk source select.All is:
0: cts_oscin_clk
1:cts_rtc_clk
2:sys_pll_div16 (internal clock)
3:ddr_pll_div32 (internal clock)
4: vid_pll
5: gp0_pll
7: hifi_pll
10:adc_dpll_clk_b3 (internal clock for debug)
11:adc_dpll_intclk (internal clock for debug)
12:clk_msr_src(select from all internal clock except PLLs);
16: no used
17: sys_cpu_clk_div16 (internal clock)
19: fclk_div2
20: fclk_div2p5
21: fclk_div3
22: fclk_div4
23: fclk_div5
24: fclk_div7
25: mpll0
26: mpll1
27: mpll2
28: mpll3
So i only added the clocks that will actually be used, and some
debugging clock peripherals will not be used.
