Make the entire combination of plls to be one single clock. The parents used
for bypasses are specified each as an index in the parents list.
The determine_rate does a lookup throughout all the possible combinations
for all the divs and returns the best possible 'setup' which in turn is used
by set_rate later to set up all the divs and bypasses.

The arm pll bypass needs to propagate the rate upwards
in order for the cpufreq to work.

The CLKO2 clock source select list is the following as per the i.MX8M
Reference Manual:
000 - 25M_REF_CLK
001 - SYSTEM_PLL2_DIV5
010 - SYSTEM_PLL1_DIV2
011 - SYSTEM_PLL2_DIV6
100 - SYSTEM_PLL3_CLK
101 - AUDIO_PLL1_CLK
110 - VIDEO_PLL1_CLK
111 - 32K_REF_CLK
However, in imx8mq_clko2_sels[] only the first four entries are correct.
Fix it by adding the missing "sys3_pll2_out" entry in order to match
the description from the manual.
