UPSTREAM: dm: treewide: Do not use the return value of simple uclass iterator

uclass_first_device/uclass_next_device return value will be removed,
don't use it.

With the current implementation dev is equivalent to !ret. It is
redundant to check both, ret check can be replaced with dev check, and
ret check inside the iteration is dead code.

gpio/rk: bank index cannot use static count

Mostly the gpios are probed not in order, so the static count is really
uncorrect most of time, remove it and report a error.
