[0/4] RISC-V: Modularize common match conditions for trigger

Message

According to RISC-V Debug specification, 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.

Alvin Chang (4):
  target/riscv: Add functions for common matching conditions of trigger
  target/riscv: Apply modularized matching conditions for breakpoint
  target/riscv: Apply modularized matching conditions for watchpoint
  target/riscv: Apply modularized matching conditions for icount trigger
