drm/i915/bw: Extract get_display_bw_params()

Browse source

Just like it is done for the platform-specific bandwidth parameters, use
a separate function named get_display_bw_params() to return the display
IP-specific parameters.  This simplifies intel_bw_init_hw() by having
just one call for each of the *_get_bw_info() functions.

v2:
  - Prefer to call get_display_bw_params() only once in
    intel_bw_init_hw() instead of having multiple calls in each of the
    affected *_get_bw_info() functions. (Jani)

v3:
  - Call get_display_bw_params() only after the check on
    HAS_DISPLAY(display). (Jani)
  - Return &gen11_bw_params only if display version is 11. (Matt)

v4:
  - Like done with get_soc_bw_params(), drop drm_WARN() when no display
    IP is matched.
