David Hildenbrand (Arm) ae751d567b mm/bootmem_info: stop marking mem_section_usage as MIX_SECTION_INFO ...

We never free the ms->usage data for boot memory sections (see
section_deactivate()). And to identify whether ms->usage was allocated
from memblock, we simply identify it by looking at PG_reserved.

Consequently, there is no need to mark ms->usage as MIX_SECTION_INFO.
Let's just stop doing that.
