Add support for dynamic pin control, that is, allow to change device pin configuration at runtime. Because no device de-initialization is available yet, this API has limited usage options, e.g. modify pin configuration at early boot stage (before device driver is initialized) Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>

This option must be selected by drivers that require access to the device

This option can be selected if the pin control configuration defined by

a driver has to be accessed externally. This can happen, for example, when
|

dynamic pin control is enabled or in testing environments.

When this option is enabled pin control configuration can be changed at
|
|
runtime. This can be useful, for example, to change the pins assigned to a
|
|
peripheral at early boot stages depending on a certain input.
