drm/bridge: tda998x: Move tda998x_create/destroy into probe and remove

Now that tda998x_create and tda998x_destroy are called only in the probe
function, there is no need for separate functions.
Move the code into the tda998x_probe and tda998x_remove functions.
Rewrite the cleanup path using goto calls in probe and reorder it in the
remove function.
