We currently have a user visible CONFIG_POWERNV_MSI option, but it
doesn't actually disable MSI for powernv. The MSI code is always built,
what it does disable is the inclusion of the MSI bitmap code, which
leads to a build error.
eg, with PPC_POWERNV=y and POWERNV_MSI=n we get:
arch/powerpc/platforms/built-in.o: In function `.pnv_teardown_msi_irqs':
pci.c:(.text+0x3558): undefined reference to `.msi_bitmap_free_hwirqs'
We don't really need a POWERNV_MSI symbol, just have the MSI bitmap code
depend directly on PPC_POWERNV.
