I debated between pci.h and kexec.h but pci-driver.c does not include
kexec.h and I didn't want to include a whole new file. Now I see another
problem with adding that extern declaration to pci.h - if CONFIG_KEXEC
is not set, build will fail. I should add #ifdef CONFIG_KEXEC to the
code in pci-driver.c as well. Time for v2.
