  MT8186, MT8192 and MT8195 use ARM DynamIQ, which combines big and
LITTLE cores in one single cluster! A two cluster topology is simply
wrong in this case.

While at it, after some research, I've also noticed that the names
assigned to the idle states are misleading, so I went on changing
them to reflect the actual function.

The names change commits, unlike the CPU map ones, didn't get any
Fixes tag, as naming changes aren't fixing anything that would be
meaningful for functionality (it's cosmetic, nothing else).

Whole series applied, thanks!
