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
