From: Laurentiu Tudor <laurentiu.tudor at nxp.com>

This allows building powerpc with the GENERIC_MSI_IRQ_DOMAIN
Kconfig by enabling the asm-generic msi.h in Kbuild. Without
this, there's a compilation error [1] because powerpc, as most
arches, doesn't provide an asm/msi.h.

[1] In file included from ./include/linux/kvm_host.h:20:0,
                 from ./arch/powerpc/include/asm/kvm_ppc.h:30,
                 from arch/powerpc/kernel/dbell.c:20:
./include/linux/msi.h:195:21: fatal error: asm/msi.h: No such file or directory

 - compilation error happens when GENERIC_MSI_IRQ_DOMAIN is enabled and not
   GENERIC_MSI_IRQ, so fix commit msg and title
