drm/amd/display: widen dc_hdmi_frl_flags.force_frl_rate to unsigned int

dc_hdmi_frl_flags.force_frl_rate mirrors dc_debug_options.force_frl_rate,
which was just widened to unsigned int. Match the type here too so the
assignment in link_hdmi_frl.c does not narrow from unsigned to signed.

All call sites in link_hdmi_frl.c only compare the value against 0, 0xF,
or an hdmi_frl_link_rate enum whose values are non-negative, so the
change is behaviour-preserving and does not introduce sign-compare
warnings.
