Subject: [PATCH v2 2/9] drm/bridge: ti-sn65dsi86: zero is never greater than an unsigned int

When we iterate over ti_sn_bridge_dp_rate_lut, there's no reason to
start at index 0 which always contains the value 0.  0 is not a valid
link rate.

This change should have no real effect but is a small cleanup.
