The bootmem area reserved for crashlog might be smaller than CRASHLOG_OFFSET
bytes, leading to an integer underflow when calculating the memory address
in crashlog_set_addr() which subsequently causes the kernel to crash when
attempting to vmap() the crashlog pages.
Change the logic to only consider the offset when the size of the used memory
area is sufficient.

Check memblock regions for sufficient size before attempting to use
them. Allow checks for multiple memblock regions until a suitable one is
found.

This can be used to prevent double compression for platforms where the
boot loader already expects compressed images.

The function memblock_insert_region() is in the section
__init_memblock, also put crashlog_init_memblock there.
This fixes this section mismatch warning:
The function memblock_insert_region.isra.1() references
the function __meminit crashlog_init_memblock().
This is often because memblock_insert_region.isra.1 lacks a __meminit
annotation or the annotation of crashlog_init_memblock is wrong.
