drm/amd/display: widen FRL debug knobs to unsigned int

Browse Source 
force_frl_rate, select_ffe and limit_ffe in dc_debug_options carry
non-negative configuration values: an FRL link-rate enum (0..0xF), an
FFE level selector and an FFE level limit. They are only ever compared
against 0/0xF, assigned, or cast to uint8_t before being written to
hardware. No call site relies on signed semantics.

Make the types unsigned int to match how the values are actually used
and to silence MISRA-style signedness warnings on internal builds.
