Revert "card: Support adding ports dynamically"

This reverts commit a9c3f2fb0f.

It has been recently agreed that ports should somehow have some physical
meaning, leading to the port merge in module-bluetooth-device.

With this assumption in mind, it is very unlikely that a card would
add or remove ports dynamically. Therefore, the core can be simplified
by removing the support for this.

The revert affects the code added to module-card-restore in commit
a1a0ad1af2, which can now be partially
removed.
