[PATCH v4 04/13] drm/bridge: tc358762: Configure SYSCTRL first

[Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>]

SYSCTRL affects the DPI output and the clock tree, but we configure it
late, when the DPI output is already enabled and clocks are running.

Move the SYSCTRL configuration to the beginning, before anything is
enabled.
