phy: Add USB speed related PHY modes
Add following USB speed related PHY modes: LS (Low Speed), FS (Full Speed), HS (High Speed), SS (Super Speed) Speed related information is required by some QCOM PHY drivers to program PHY monitor resume/remote-wakeup events in suspended state. Speed is needed in order to set correct polarity of wakeup events for detection. E.g. QUSB2 PHY monitors DP/DM line state depending on whether speed is LS or FS/HS to detect resume. Similarly QMP USB3 PHY in SS mode should monitor RX terminations attach/detach and LFPS events depending on SSPHY is active or not.
