Before SLUB initialization, various subsystems used memblock_alloc to
allocate memory. In most cases, when memory allocation fails, an immediate
panic is required. To simplify this behavior and reduce repetitive checks,
introduce `memblock_alloc_or_panic`. This function ensures that memory
allocation failures result in a panic automatically, improving code
readability and consistency across subsystems that require this behavior.

Changelog:
----------
v1: initial version
v2: add __memblock_alloc_or_panic support panic output caller
v3: panic output phys_addr_t use printk's %pap
v4: make __memblock_alloc_or_panic out-of-line, move to memblock.c
v6: Fix CI compile error

If people commented on your patch it does not mean you should add
Reviewed-by or Acked-by tags for them. Wait for explicit tags from the
reviewers.

And:

 - Acked-by: indicates an agreement by another developer (often a
   maintainer of the relevant code) that the patch is appropriate for
   inclusion into the kernel. 

I'm not a maintainer so I even don't have the right to use Acked-by :).
