[PATCH 02/10] Bluetooth: Add specific connection parameter clear functions

[johan.hedberg@xxxxxxxxx]

From: Johan Hedberg <johan.hedberg@xxxxxxxxx>

In some circumstances we'll need to either clear only the enabled
parameters or only the disabled ones. This patch adds convenience
functions for this purpose.
