This commit aims to remove the confusing real & fake port variables
and improve how slot ID is found using fake port.

Clarification on real and fake ports:
  - 'real port' refers to a unique hardware port number.
  - 'fake_port' refers to the port number within a port hub. Its only
    function is to facilitate the identification of the slot ID,
    this process is very inefficient.

Niklas Neronin (3):
  xhci: rework how real & fake ports are found
  xhci: replace real & fake port with pointer to root hub port
  xhci: save slot ID in struct 'xhci_port'
