PCI: endpoint: Fix Kconfig dependency
If CONFIG_NTB is not set and CONFIG_PCI_EPF_VNTB is y.
make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-, will be failed, like this:
drivers/pci/endpoint/functions/pci-epf-vntb.o: In function `epf_ntb_cmd_handler':
pci-epf-vntb.c:(.text+0x95e): undefined reference to `ntb_db_event'
pci-epf-vntb.c:(.text+0xa1f): undefined reference to `ntb_link_event'
pci-epf-vntb.c:(.text+0xa42): undefined reference to `ntb_link_event'
drivers/pci/endpoint/functions/pci-epf-vntb.o: In function `pci_vntb_probe':
pci-epf-vntb.c:(.text+0x1250): undefined reference to `ntb_register_device'
The functions ntb_*() are defined in drivers/ntb/core.c, which need CONFIG_NTB setting y to be build-in.
To fix this build error, add depends on NTB.
