According to latest RISC-V Debug specification version 1.0 [1], the enabled privilege levels of the trigger is common match conditions for all the types of the trigger.
This series modularize the code for checking the privilege levels of type 2/3/6 triggers by implementing functions trigger_common_match() and trigger_priv_match(). Additional match conditions, such as CSR tcontrol and textra, can be further implemented into trigger_common_match() in the future.

Changes from v1: - Fix typo - Add commit description for changing behavior of looping the triggers when we check type 2 triggers.
