[Minios-devel] [UNIKRAFT PATCH v3 4/4] include: Merge ctors.h with plat/ctors.h

[Vlad-Andrei BĂDOIU (78692) <vlad_andrei.badoiu@xxxxxxxxxxxxxxx>]

We merge the two headers because they share the same purpose. This patch
moves the content of include/uk/plat/ctors.h to include/uk/ctors.h,
adapts the naming from ukplat_ctor_* to uk_ctor_* and adapts the boot.c
files to work with the new changes.
