This series borrows the concept used on Tegra234 to scale EMC based on
CPU frequency and applies it to Tegra186 and Tegra194. Except that the
bpmp on those archs does not support bandwidth manager, so the scaling
iteself is handled similar to how Tegra124 currently works.

It applies on v6.18-rc3, but not next. Your cleanup series caused the
conflict. I'll rebase on next-20251027 and resend.

Patches should apply on maintainer's for-next branches, not mainline.
My cleanup series were applied two weeks ago, so week or more before you
sent it.
