When _param is unsigned and the minimum value of range is 0,
CHECK_RANGE macro gives the following warning:
COVERITY NO_EFFECT: This less-than-zero comparison of an unsigned value
is never true.
So I changed the type of hird_threshold from u8 to int to avoid that
warning.

Here are two little fixes for LPM feature.
First one is coverity warning fix.
The Second one was asserted by Stefan Wahren.
Changes from version 0:

to int, changed hird_threshold type from u8 to int.

This series contains patches which are already have been sent in
"usb: dwc2: fixes, enhancements and new features" series.
That patch series was too large, and based on community feedbacks decided to
split that series into small pieces. This is a fourth and last part.
In this series we included
dwc2_force_mode_if_needed() function since the "if
needed" part is already taken care of by the polling in
dwc2_force_mode().
Finally, remove all other calls to dwc2_clear_force_mode().
