usb: xhci: rename parameter to match argument 'portsc'

A previous patch renamed the temporary variable holding the value read
from the PORTSC register from 'temp' to 'portsc'. This patch follows up
by updating the parameter names of all helper functions called from
xhci_hub_control() that receive a PORTSC value, as well as the functions
they call.

Function changed:
xhci_get_port_status()
 L xhci_get_usb3_port_status()
    L xhci_hub_report_usb3_link_state()
    L xhci_del_comp_mod_timer()
xhci_get_ext_port_status()
xhci_port_state_to_neutral()
xhci_clear_port_change_bit()
xhci_port_speed()

The reason for the rename is to differentiate between port
status/change bit to be written to PORTSC and replying to hub-class
USB requests. Each of them use their specific macros.

Use "portsc" name for PORTSC values and "status" for values intended
for replying to hub-class USB request.

A dedicated structure for USB hub port status responses
('struct usb_port_status' from ch11.h) exists and will be integrated in
a later patch.
