Kai-Heng Feng d6522bc320 xhci: Return if xHCI doesn't support LPM
commit f0c472a6da upstream.

Just return if xHCI is quirked to disable LPM. We can save some time
from reading registers and doing spinlocks.

Add stable tag as we want this patch together with the next one,
"Poll for U0 after disabling USB2 LPM" which fixes a suspend issue
for some USB2 LPM devices
