powerpc: Add Kconfig dependency on PCI_MSI for XICS and select for PSERIES
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
Furthermore, as noted by Benjamin Herrenschmidt, "CONFIG_XICS should be
made invisible and selected by PSERIES."
This patch adds the dependency in KConfig for XICS on PCI_MSI. When PSERIES
support is being configured, both options are silently selected.
