I think you started to use BCMA_DRIVER_corename. Could you stick to it
(one schema), please? Maybe just
BCMA_DRIVER_PCI_HOSTMODE
?

Does it make sense to init hostmode PCI like clientmode if we just
disable CONFIG_BCMA_PCICORE_HOSTMODE?

I think we should always check if core is host or client mode and use
correct initialization only. We should not init it as clientmode just
because we do not have driver for host mode.

Please rename "PCI Core", add something about hostmode.
