x86-64: Calgary: fix section mismatch warnings in tce

Fix section mismatch warnings:
these functions are called only from __init functions.

WARNING: vmlinux.o(.text+0x1861c): Section mismatch: reference to .init.text:free_bootmem (between 'free_tce_table' and 'build_tce_table')
WARNING: vmlinux.o(.text+0x187e5): Section mismatch: reference to .init.text:__alloc_bootmem_low (between 'alloc_tce_table' and 'kretprobe_trampoline_holder')
