[PATCH] PCI: keystone: Refactor Kconfig for RC/EP mode

[Kishon Vijay Abraham I]

Do not allow PCI_KEYSTONE to be visible to user and let user visible
CONFIG symbols PCI_KEYSTONE_HOST and PCI_KEYSTONE_EP select
PCI_KEYSTONE. This will let pci-keystone.c to be compiled only when
either PCI_KEYSTONE_HOST or PCI_KEYSTONE_EP is selected.
