[Intel-gfx] [PATCH] drm/i915: Remove bogus LPT iCLKIP WARN

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The WARN shouldn't have been added yet. For the moment the
clock that gets passed here is just what the user has requested
(via the modeline) and may not be exactly what iCLKIP can
generate.

Later on the plan is to change things so that we already get
passed the exact clock here, at which point the WARN should
be reintroduced.

Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/6246
Fixes: 97708335b04d ("drm/i915: Introduce struct iclkip_params")
