History
Justin Hammond 82fb0d8d06 drivers/usbhost: Separate the xHCI driver from the PCI bus. 
Nothing in the controller driver is PCI-specific beyond finding the
registers and the interrupt, so an SoC wiring an xHCI controller
directly could not use any of it.

usbhost_xhci.c is now the driver; usbhost_xhci_pci.c is the PCI
attachment, holding the ID table, the BAR mapping and the MSI-X vector.
include/nuttx/usb/xhci.h carries what passes between them: the register
base, a way to attach the interrupt, and a name to report the controller
by, since a system may have more than one.

The interrupt belongs to the bus: the bus attaches and detaches it, and
the driver never holds an interrupt number.

USBHOST_XHCI is the driver and is not selectable on its own;
USBHOST_XHCI_PCI selects it.  Another bus adds its own symbol beside it.

No functional change intended.
