drivers/intel/usb4: Update driver to support Retimer firmware upgrade
Along with upstream kernel for Retimer firmware upgrade, coreboot
provides DFPx under host router where each DFP has its PLD and DSM. The
DFPx's functions encapsulates power control through GPIO, PD
suspend/resume and modes setting for Retimer firmware update under NDA
scenario.
BUG=b:186521258
TEST=Booted to kernel and validated host router's DFPx properties after
decomposing SSDT table.
