From: Alvin Chang <alvi...@andestech.com> According to RISC-V Debug specification ratified version 0.13 [1] (also applied to version 1.0 [2] but it has not been ratified yet), 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.
