ANDROID: Revert "cpufreq: Avoid using inconsistent policy->min and policy->max"

The combination of the cpufreq changes that came in with v6.12.28,
commit 573b0472 ("cpufreq: Avoid using inconsistent
policy->min and policy->max") and commit 962d8830 ("cpufreq:
Fix setting policy limits when frequency tables are used")
unfortunately broke the KABI.

The second of which was reverted in ad2b007e ("Revert
"cpufreq: Fix setting policy limits when frequency tables are
used"").

However, that change is actually a necessary fix to the first.
As the refactoring to passing the max and min through the
arguments couldn't be done without KABI impact, the
changes to be more consistent with policy->min/max ends up
introducing a subtle problem where the new max value being
set ends up being clamped to the current max value - thus
cpufreq max can be reduced but not increased (with the
min increased but not decreased).

A minimal fix of this effectively undoes the key point of
commit 573b0472, so it seems best to revert the whole thing
for now.

I think the small pre-existing risk of the policy->max/min values
being read when shortly to an intermediate value before getting
assigned the final value seems to be less problematic in practice.
