of/pdt: fix section mismatch warning

Fix the following section mismatch warning - seen when building sparc32:

WARNING: vmlinux.o(.text+0x1ff9c0): Section mismatch in reference from the function kernel_tree_alloc() to the function .init.text:prom_early_alloc()
The function kernel_tree_alloc() references
the function __init prom_early_alloc().
This is often because kernel_tree_alloc lacks a __init
annotation or the annotation of prom_early_alloc is wrong.

prom_early_alloc() is annotated __init, and users of
kernel_tree_alloc() is also annotated __init.
So simply match the annoation of these to fix the warning.
