The cyclic mode uses two member variables in struct DumpInfo to store
the cyclic region each time. Since there's a global instance of struct
DumpInfo, then those two member variables, cyclic_start_pfn and
cyclic_end_pfn would be the same as global variable on behavior. So
with this attribute, the
v1-v2:
In first_cycle(), start_pfn assignation is not aligned to info-pfn_cyclic.
Now in v2 change this. Accordingly the pfn in write_elf_header() and
write_elf_pages_cyclic() need be adjusted to the real beginning of a
load segment, but not the cycle-start_pfn which may be lower
Now member variables to store cyclic pfn region in struct DumpInfo
is not needed any more, remove them.

Per struct cycle and the relevant helper functions, it's simple to
update cyclic region only. update_cyclic_region() is broken and not
needed any more. cycle containing the cyclic region is passed down,
and not global.
Related clean up is also done in this patch.
