From: Michael Ellerman <mpe@ellerman.id.au>

[ Upstream commit 4cfa6ff24a9744ba484521c38bea613134fbfcb3 ]

When building ppc64_book3e_allmodconfig the build fails with:

arch/powerpc/kexec/file_load_64.c:1063:14: error: implicit declaration of function ‘firmware_has_feature’
1063 | if (!firmware_has_feature(FW_FEATURE_LPAR))
| ^~~~~~~~~~~~~~~~~~~~

Add a direct include of asm/firmware.h to fix the error.
