swiotlb: add missing __init annotations
Impact: cleanup, reduce kernel size a bit
The current kernel build warns:
WARNING: vmlinux.o(.text+0x11458): Section mismatch in reference from the function swiotlb_alloc_boot() to the function .init.text:__alloc_bootmem_low()
The function swiotlb_alloc_boot() references
the function __init __alloc_bootmem_low().
This is often because swiotlb_alloc_boot lacks a __init
annotation or the annotation of __alloc_bootmem_low is wrong.
WARNING: vmlinux.o(.text+0x1011f2): Section mismatch in reference from the function swiotlb_late_init_with_default_size() to the function .init.text:__alloc_bootmem_low()
The function swiotlb_late_init_with_default_size() references
the function __init __alloc_bootmem_low().
This is often because swiotlb_late_init_with_default_size lacks a __init
annotation or the annotation of __alloc_bootmem_low is wrong.
and indeed the functions calling __alloc_bootmem_low() can be marked
__init as well.
