libpayload: xhci: Fix CAPREG address calculation
I rushed CB:40895 in to fix a bug only to introduce another. xhci_init() no longer crashes, but it doesn't correctly initialize the XHCI controller either, and unfortunately the error messages are all hidden behind USB_DEBUG. This patch fixes the incorrect address calculation to what it was before CB:39838.
