[PATCH v2 00/14] Correct confusing lmb error message

[Simon Glass]

I ran into a very confusing error message about overlapping memory. I
found that the message is not correct, so this series refactors the lmb
code a little to permit the real message to be displayed, which is that
the internal lmb table has overflowed.

It also tidies up the code a little.

Feedback on the initial series showed some confusion between one type of
region and another. I had the same confusion, so this series renames the
inner 'region' to 'area'.

Changes in v2:
- Add new patch to rename region array to area
- Add new patch to rename memory/reserved_regions to area
- Add new patch to rename LMB_MAX_REGIONS and LMB_USE_MAX_REGIONS
- Add new patch to rename LMB_MAX_REGIONS and LMB_USE_MAX_REGIONS
- Add new patch to update use of region in the header file
- Add new patch to update use of region in the C file
