This adds initial support for the Sdtrig extension via the Trigger
Module, as defined in the RISC-V Debug Specification [1].
Only "Address / Data Match" trigger (type 2) is implemented as of now,
which is mainly used for hardware breakpoint and watchpoint. The number
of type 2 triggers implemented is 2, which is the number that we can
find in the SiFive U54/U74 cores.
