lib: utils/timer: Simplify MTIMER synchronization
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.
