[PATCH v3 01/15] drm/connector: hdmi: Evaluate limited range after computing format

[Cristian Ciocaltea]

Evaluating the requirement to use a limited RGB quantization range
involves a verification of the output format, among others, but this is
currently performed before actually computing the format, hence relying
on the old connector state.

Move the call to hdmi_is_limited_range() after hdmi_compute_config() to
ensure the verification is done on the updated output format.

connector state")
