  The infracfg driver cannot be converted to clk_mtk_simple_probe() as
it registers cpumuxes, which is not supported on the common probing
mechanism: for this reason, move it to its own file.

While at it, also convert it to be a platform driver instead.

Implementing error handling deserves a separate commit, or at least a mention.

Something just ticked in my brain and I think you even said that already in
a previous review?

In that case, I'm sorry for apparently ignoring that. Count that done for v3!
