assigned-clock-rates would set GCC_GP1_CLK_SRC rate, and automatically
select the proper parent clock best suited for rate.

However, as per discussion in
https://patchwork.kernel.org/project/linux-samsung-soc/patch/20240618-starqltechn_integration_upstream-v3-2-e3f6662017ac@xxxxxxxxx
the old approach with additional freq_tbl entries was criticised. New
approach, introduced in
https://lore.kernel.org/all/20241007-starqltechn_integration_upstream-v6-0-dd75c06c708d@xxxxxxxxx/
automatically calculates m/n/d values for GP clock, but it cannot
select best suited parent - it's user responsibility.
