usb: dwc2: disable lpm feature on Rockchip SoCs

LPM feature of DWC2 module integrated in Rockchip SoCs doesn't work
properly or needs some additional handling, so disable it for now.
Without disabling LPM feature, the USB ADB communication fail with
the following error log:

dwc2 ff580000.usb: new address 27
dwc2 ff580000.usb: Failed to exit L1 sleep state in 200us.
dwc2 ff580000.usb: dwc2_hsotg_send_reply: cannot queue req
dwc2 ff580000.usb: dwc2_hsotg_process_req_status: failed to send reply
dwc2 ff580000.usb: dwc2_hsotg_enqueue_setup: failed queue (-11)
dwc2 ff580000.usb: Failed to exit L1 sleep state in 200us.

[diff vs vendor kernel: added lpm_clock_gating, besl and
 hird_threshold_en settings as seen in  commit 53febc95
