usb: cdnsp: Fix issue with CV Bad Descriptor test

[ Upstream commit 2831a81077f5162f104ba5a97a7d886eb371c21c ]

The SSP2 controller has extra endpoint state preserve bit (ESP) which
setting causes that endpoint state will be preserved during
Halt Endpoint command. It is used only for EP0.
Without this bit the Command Verifier "TD 9.10 Bad Descriptor Test"
failed.
Setting this bit doesn't have any impact for SSP controller.
