Subject: [PATCH v1 9/9] drm/bridge: tc358768: remove unused variable

From: Francesco Dolcini <francesco.dolcini@...adex.com>

Remove the unused phy_delay_nsk variable, before it was wrongly used
to compute some register value, the fixed computation is no longer using
it and therefore can be removed.
