[PATCH 2/2] dm: core: Add a way to skip powering down power domains

[sjg at google.com]

When removing a device the power domains it uses are generally powered
off. But when we are trying to unbind all devices (e.g. for running tests)
we don't want to probe a device in the 'remove' path.

Add a new flag to skip this power-down step.
