Remove the unused field size of struct lmb_region as it is initialized to 0
and never used after in lmb library.
See Linux kernel commit 4734b594c6ca ("memblock: Remove memblock_type.size
and add memblock.memory_size instead")

Move lmb property arrays to struct lmb and manage the array size in
a the new element 'max' of struct lmb_region. This modification allows
to update its size independently in the next patch.
see Linux kernel commit bf23c51f1f49 ("memblock: Move memblock arrays
to static storage in memblock.c and make their size a variable")

Add 2 configs CONFIG_LMB_MEMORY_REGIONS and CONFIG_LMB_RESERVED_REGIONS
to change independently the max number of the regions in lmb
library.
Increase CONFIG_LMB_RESERVED_REGIONS is useful to avoid lmb errors in
bootm when the number of reserved regions (not adjacent) is reached:
+ 1 region for relocated U-Boot
+ 1 region for initrd
+ 1 region for relocated linux device tree
+ reserved memory regions present in Linux device tree.
The current limit of 8 regions is reached with only 5 reserved regions
in DT.

For the latest kernel device tree the max number of reserved regions
in lmb library is reached: 8 with 5 reserved regions in device tree.
When a new region is added, the lmb allocation for the device tree
relocation failed and boot with ramdisk failed.
This patch avoid this issue by increasing the max number of
supported reserved memory in lmb library.

This series causes a little bit of size growth everywhere. It's fatal
on nokia_rx51 (and caught via the test script). We can bring nokia_rx51
back under size by disabling the optimized memcpy/memset functions, but
that's not ideal. Can we do your changes here in a more size-concious
way? Thanks!
