mm/sparse: remove SECTION_MARKED_PRESENT

All present section iterators run before memory hotplug added any further
memory sections, Therefore, we can simply use the SECTION_IS_EARLY flag by
setting that flag earlier in sparse_sections_init().

Get rid of SECTION_MARKED_PRESENT entirely and rename
for_each_present_section_nr() to for_each_early_section_nr().

Take care of the .clang-format for_each_present_section_nr() handling.

No functional change intended.
