[RFT] powerpc/boot: Fix missing crc32poly.h when building with KERNEL_XZ

From: Krzysztof Kozlowski
Date: Wed Aug 29 2018 - 03:32:33 EST

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

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
