Fix pwmio on iMX RT.
It now handles deinit, never_reset and sharing tracking. PWM
now runs in the WAIT state as well during a time.sleep().

_reset_ok() was removed because it was called in one spot right
before deinit().

Some PWMOut were also switched to a bitmap for use instead of
reference count. That way init and deinit are idempotent.

Fixes #6589. Fixes #4841. Fixes #4541.
