Because:
#if defined(CONFIG_USB_UHCI) || defined(CONFIG_USB_OHCI) || \
     defined(CONFIG_USB_EHCI) || defined(CONFIG_USB_OHCI_NEW) || \
     defined(CONFIG_USB_SL811HS) || defined(CONFIG_USB_ISP116X_HCD) || \
     defined(CONFIG_USB_R8A66597_HCD) || defined(CONFIG_USB_DAVINCI) || \
     defined(CONFIG_USB_OMAP3) || defined(CONFIG_USB_DA8XX) || \
     defined(CONFIG_USB_BLACKFIN) || defined(CONFIG_USB_AM35X)
...
#else
#error USB Lowlevel not defined
#endif

All of these definitions are usb host implementation (maybe OTG too) but pxa
cannot be host.
