ARM: defconfig: kill remnants of CONFIG_LEDS

CONFIG_LEDS was replaced by CONFIG_NEW_LEDS over ten years ago with commit
fa8bbb13

 ("ARM: use new LEDS CPU trigger stub to replace old one"),
but some defconfig files still reference it.

Replace it and its sub-options with the corresponding new versions.

Some of these machines may not actually have a new-style LED driver,
and I did not check them individually as most of the machines are
going away soon anyway.
