kernel: enable CONFIG_USB_PCI for PCI usb modules

With upstream commit 2c93e790e825 ("usb: add CONFIG_USB_PCI for system
have both PCI HW and non-PCI based USB HW") the CONFIG_USB_PCI was
introduced.

The option is disabled by default in our generic kernel 4.14 config, hence
we need to set the option for all related kernel modules.
