mm: memblock: add more debug logs
It is useful to know the exact caller of memblock_phys_alloc_range() to
track early memory reservations during development.
Currently, when memblock debugging is enabled, the allocations done with
memblock_phys_alloc_range() are only reported at memblock_reserve():
[ 0.000000] memblock_reserve: [0x000000023fc6b000-0x000000023fc6bfff] memblock_alloc_range_nid+0xc0/0x188
Add memblock_dbg() to memblock_phys_alloc_range() to get details about
its usage.
For example:
[ 0.000000] memblock_phys_alloc_range: 4096 bytes align=0x1000 from=0x0000000000000000 max_addr=0x0000000000000000 early_pgtable_alloc+0x24/0x178
[ 0.000000] memblock_reserve: [0x000000023fc6b000-0x000000023fc6bfff] memblock_alloc_range_nid+0xc0/0x188
