helpers: new macro to CLAMP high threshold only

Browse Source 
Useful when clamping a unsigned integer with low threshold set to 0,
which would give us compiler warnings with -Wtype-limits when using
CLAMP(), e.g.:

  via/mm-broadband-modem-via.c: In function ‘handle_evdo_quality_change’:
  /usr/include/glib-2.0/glib/gmacros.h:811:63: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]
    811 | #define CLAMP(x, low, high)  (((x) > (high)) ? (high) : (((x) < (low)) ? (low) : (x)))
        |                                                               ^
  via/mm-broadband-modem-via.c:284:19: note: in expansion of macro ‘CLAMP’
    284 |         quality = CLAMP (quality, 0, 100);
        |                   ^~~~~
