libpayload: add controller type in usbdev_hc
Add controller type (UHCI, OHCI, EHCI or XHCI) into usbdev_hc (hci_t) struct, so now we know which type selected controller have. It needed to access controller specific data, if access usb tree outside of libpayload (e.g. in payload intself) Change-Id: I7df947bbb56a50d0d792ccd4d3a6b021ee95e2ea Signed-off-by: Anton Kochkov <anton.kochkov@gmail.com> Reviewed-on: http://review.coreboot.org/1145 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
