This is v2 of the OF reserved memory fixes/cleanups series.

The original v1 [1] contains two parts of work:
 - Bug fixes and small cleanups about reserved memory. 
 - A vmcore size optimization that exclude reserved memory out of
   vmcore.

For the convenience of review, I have split it into two independent
patchsets. This patchset only contains bug fixes and cleanups
content, while the content optimized for vmcore size will be in
another patchset.

v1 --> v2:
1. Add new patch 1, to fix unnecessary memory allocation.
2. Support only one entry in reg property in patch 3, suggested by
   Rob Herring [2].
3. Per Rob's review on v1 2/11 [3], drop patch about "rejecting
   reserved memory outside physical memory range" due to potential
   abuse.
4. Drop patch about "of: reserved_mem: avoid unconditional save of
   reg entries in fdt_scan_reserved_mem_late()" due to a
   misunderstanding on my side.
5. Update commit message.
