[Qemu-riscv] [PATCH-for-4.2 2/3] hw/usb/Kconfig: Add CONFIG_USB_EHCI_PCI

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

The USB_EHCI entry currently include PCI code. Since the EHCI
implementation is already split in sysbus/PCI, add a new
USB_EHCI_PCI. There are no logical changes, but the Kconfig
dependencies tree is cleaner.
