Add lmb_dump_region() function, to simplify lmb_dump_all_force().
This patch is based on Linux memblock dump function.

An example of bdinfo output is:

.....
fdt_size    = 0x000146a0
FB base     = 0xfdd00000
lmb_dump_all:
 memory.cnt  = 0x1
 memory[0] [0xc0000000-0xffffffff], 0x40000000 bytes flags: 0
 reserved.cnt  = 0x6
 reserved[0] [0x10000000-0x10045fff], 0x00046000 bytes flags: 4
 reserved[1] [0x30000000-0x3003ffff], 0x00040000 bytes flags: 4
 reserved[2] [0x38000000-0x3800ffff], 0x00010000 bytes flags: 4
 reserved[3] [0xe8000000-0xefffffff], 0x08000000 bytes flags: 4
 reserved[4] [0xfbaea344-0xfdffffff], 0x02515cbc bytes flags: 0
 reserved[5] [0xfe000000-0xffffffff], 0x02000000 bytes flags: 4
arch_number = 0x00000000
TLB addr    = 0xfdff0000
