[PATCH 1/4] powerpc: Add Kconfig dependency for PCI_MSI as needed by XICS

[Mel Gorman]

It's possible to set CONFIG_XICS without CONFIG_PCI_MSI. When that
happens, the kernel fails to build with

arch/powerpc/platforms/built-in.o: In function `.xics_startup':
xics.c:(.text+0x12f60): undefined reference to `.unmask_msi_irq'
make: *** [.tmp_vmlinux1] Error 1

This patch adds the dependency in KConfig.
