leds: is31fl319x: Cleanup formatting and dev_dbg calls
Fix remaining non-standard place for comments.
Remove remaining dev_dbg after regmap_read in is31fl3196_brightness_set.
Remove __func__ in dev_dbg calls, instead adding "channel" string to
describe the first displayed value.
Change remaining container_of() call to be on one line,
as well as a few others.
