Subject: powerpc/boot: Fix missing crc32poly.h when building with KERNEL_XZ
Origin: https://patchwork.ozlabs.org/patch/963258/
After commit faa16bc404d7 ("lib: Use existing define with
polynomial") the lib/xz/xz_crc32.c includes a header from include/linux
directory thus any other user of this code should define proper include
path.
This fixes the build error on powerpc with CONFIG_KERNEL_XZ:
In file included from ../arch/powerpc/boot/../../../lib/decompress_unxz.c:233:0,
from ../arch/powerpc/boot/decompress.c:42:
../arch/powerpc/boot/../../../lib/xz/xz_crc32.c:18:29: fatal error: linux/crc32poly.h: No such file or directory
