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.
