drm/bridge: analogix_dp: Remove the unnecessary calls to clk_disable_unprepare() during probing

With the commit f37952339cc2 ("drm/bridge: analogix_dp: handle clock via
runtime PM"), the PM operations can help enable/disable the clock. The
err_disable_clk label and clk_disable_unprepare() operations are no
longer necessary because the analogix_dp_resume() will not be called
during probing.
