usb: dwc3: Fix default lpm_nyet_threshold value
The max possible value for DCTL.LPM_NYET_THRES is 15 and not 255. Change the default value to 15. Cc: stable@vger.kernel.org Fixes: 80caf7d21adc ("usb: dwc3: add lpm erratum support") Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
