usb: xhci: separate use of USB Chapter 11 PLS macros from xHCI-specific PLS macros

The xhci driver uses two different sources for Port Link State (PLS):
  1. The PLS field in the PORTSC register (bits 8:5).
  2. The PLS value encoded in bits 15:8 of the USB request wIndex,
     received by xhci_hub_control().

While both represent similar link states, they differ in a few details,
for example, xHCI's Resume State. Because of these differences, the xhci
driver defines its own set of PLS macros in xhci-port.h, which are intended
to be used when reading and writing  PORTSC. The generic USB Chapter 11
macros in ch11.h should only be used when parsing or replying to hub-class
USB requests.

To avoid mixing these two representations and prevent incorrect state
reporting, replace all uses of Chapter 11 PLS macros with the xHCI
versions when interacting with the PORTSC register.
