regulator: output current-limit for all regulators in summary

Browse source

Voltage regulators can have (unregulated) current limits too, so we should
probably output both voltage and current for all regulators.

Holding the rdev->mutex actually conflicts with _regulator_get_current_limit
but also is not really necessary, as the global regulator_list_mutex already
protects us from the regulator vanishing while we go through the list.

On the rk3288-firefly the summary now looks like:

 regulator                      use open bypass voltage current     min     max
