swd: Remove DAP from parameter list

Making the SWD driver aware of the DAP that controls it is a layering
violation.

The only usage for the DAP pointer is to store the number of idle cycles
the AP may need to avoid WAITs. Replace the DAP pointer with a cycle
count hint instead to avoid future misuse.
