As I was testing to make sure that the DEFER path worked well with my patch series, I got tired of seeing this scary message in my logs just because the panel needed to defer: [drm:ti_sn_bridge_probe] *ERROR* could not find any panel node
Let's use dev_err_probe() which nicely quiets this error and also simplifies the code a tiny bit. We'll also update other places in the file which can use dev_err_probe().
