usb: cdnsp: fix L1 resume issue for RTL_REVISION_NEW_LPM version

commit 8614ecdb1570e4fffe87ebdc62b613ed66f1f6a6 upstream.

The controllers with rtl version larger than
RTL_REVISION_NEW_LPM (0x00002700) has bug which causes that controller
doesn't resume from L1 state. It happens if after receiving LPM packet
controller starts transitioning to L1 and in this moment the driver force
resuming by write operation to PORTSC.PLS.
It's corner case and happens when write operation to PORTSC occurs during
device delay before transitioning to L1 after transmitting ACK
time (TL1TokenRetry).

Forcing transition from L1->L0 by driver for revision larger than
RTL_REVISION_NEW_LPM is not needed, so driver can simply fix this issue
through block call of cdnsp_force_l0_go function.
