We simplify MTIMER synchronization as follows: 1) Detect MTIMER devices with unique (or non-shared) MTIME register at boot-time 2) Select first MTIMER device with no associated HART as our reference MTIMER device 3) Only synchronize MTIMER devices with unique (or non-shared) MTIME register using reference MTIMER device 4) Directly update the MTIME register at time of synchronization because MTIME is a read/write register.
