#     powerpc/64e: Fix kexec build error
#     
#     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.
#     
#     Fixes: b1fc44eaa9ba ("pseries/iommu/ddw: Fix kdump to work in absence of ibm,dma-window")
