Mcontrol6

Created by: silabs-oysteink

Added the following features for trigger type 6 (mcontrol6):

• Instruction address checks depend on M/U bit and actual privilege level
• tdata1.match {0,2,3} selects comparison {==, >= <}
• LSU address match, also with privilege checks and tdata1.match checks -- LSU will not create an externally visible OBI request on trigger match -- Matching is enabled for PUSH/POP mid sequence
