dpll: add STATE_CONNECTED_OVERRIDE pin capability
Add DPLL_PIN_CAPABILITIES_STATE_CONNECTED_OVERRIDE capability flag
that indicates a pin can be set to connected regardless of the
current DPLL device mode, overriding the active input selection.
This is useful for automatic-only DPLL devices where mode cannot
be switched to manual, allowing userspace to directly connect
such pin from automatic mode.
The capability requires STATE_CAN_CHANGE to be set as well;
dpll_pin_register() warns if a driver violates this.
Document the new capability in the Pin selection section of
Documentation/driver-api/dpll.rst.
