Subject: [PATCH 1/2] memblock: remove memblock_{set,clear}_region_flags

The memblock API provides dedicated helpers to set or clear a flag on a
memory region, e.g. memblock_{mark,clear}_hotplug().

The memblock_{set,clear}_region_flags() functions are used only by the
memblock internal function that adjusts the region flags.
Drop these functions and use open-coded implementation instead.
