As VIOPATH is iSeries code and is only used by the iSeries code, the 
requirment should be

depends on PPC_PSERIES || (PPC_ISERIES && VIOPATH)

except VIOPATH isn't selectable:

arch/powerpc/platforms/iseries/Kconfig:

  config VIOPATH
         bool
         depends on VIODASD || VIOCD || VIOTAPE || ISERIES_VETH
         default y

so instead we should be adding

select VIOPATH if PPC_ISERIES

to SCSI_IBMVSCSI and just

select VIOPATH

to HVC_ISERIES as it depends on PPC_ISERIES

otherwise you have to enable one driver to get these other drivers.
