[PATCH 65/66] drm/amd/display: Use unsigned types for FRL cap check params and HPO read_state

[Chenyu Chen <chen-yu.chen@amd.com>]

[Why]
Commit c3fb1fb9e65f ("drm/amd/display: Fix warnings") aligned the
signedness of a large number of DC values, but two hunks of the original
change were not carried over:

- struct frl_cap_chk_params_fixed31_32 still declares audio_packet_type,
  h_active and h_blank as int. All three only ever hold non-negative
  values: h_active and h_blank are HDMI timing quantities counted in
  pixels, and audio_packet_type is only compared against the positive
  HDMI audio packet type constants 0x02, 0x07, 0x08, 0x09 and 0x0e in
  frl_capacity_computations_common().

- hpo_enc3_read_state() still declares pixel_encoding, color_depth and
  odm_combine as int and passes their addresses to REG_GET_2()/REG_GET(),
  whose generic_reg_get*() backends take uint32_t *. The mismatch is only
  hidden by the explicit (uint32_t *) cast inside the REG_GET macros. The
  DCN401 equivalent, hpo_enc401_read_state(), already uses uint32_t.

[How]
Widen the three struct fields to unsigned int/uint32_t and the three
locals to uint32_t so the types match how the values are produced and
consumed. No computed value changes.
