memblock: drop memblock_alloc_base()

The memblock_alloc_base() function tries to allocate a memory up to the
limit specified by its max_addr parameter and panics if the allocation
fails.  Replace its usage with memblock_phys_alloc_range() and make the
callers check the return value and panic in case of error.
