initcall: Move to inline function

an array, calling all our tiny init stubs sequentially via indirect
function calls (which can't be speculated, so they are slow).

The solution to that is pretty easy though. All we need to do is inline
the function that loops through the functions and the compiler will
automatically convert almost all indirect calls into direct inlined code.

Errata i929 in certain OMAP5/DRA7XX/AM57XX silicon revisions
(SPRZ426D - November 2014 - Revised February 2018 [1]) mentions
unexpected tuning pattern errors. A small failure band may be present
in the tuning range which may be missed by the current algorithm.
Furthermore, the failure bands vary with temperature leading to
different optimum tuning values for different temperatures.

As suggested in the related Application Report (SPRACA9B - October 2017
- Revised July 2018 [2]), tuning should be done in two stages.
In stage 1, assign the optimum ratio in the maximum pass window for the
current temperature. In stage 2, if the chosen value is close to the
small failure band, move away from it in the appropriate direction.
