Mathias Nyman 84e2e57769 usb: acpi: add helper to check port lpm capability using acpi _DSM
commit cd702d18c882d5a4ea44bbdb38edd5d5577ef640 upstream.

Add a helper to evaluate ACPI usb device specific method (_DSM) provided
in case the USB3 port shouldn't enter U1 and U2 link states.

This _DSM was added as port specific retimer configuration may lead to
exit latencies growing beyond U1/U2 exit limits, and OS needs a way to
find which ports can't support U1/U2 link power management states.

This _DSM is also used by windows:
