MT8195 clock drivers were encapsulated in one single (and big) Kconfig
option: there's no reason to do that, as it is totally unnecessary to
build in all or none of them.
Split them out: keep boot-critical clocks as bool and allow choosing
non critical clocks as tristate.

One other thing. If a Kconfig option immediately follows its dependency,
then it gets indented nicely in menuconfig, but only if.
If other options are interspersed, then the indentation gets reset.
So could you reorder the options to follow the dependency graph?
Also how you chose the dependencies should be mentioned in the commit log.
These are pure run time dependencies, not compile time nor link/load ones.
Last, I think an argument could be made against the proliferation of
Kconfig options, as it dramatically increases the combinations of
allrandconfigs. Maybe Arnd (who IIRC frequently runs allrandconfig)
could chime in on whether this is actually a concern or not.

Not sure why this option is here, out of order?
