hw/sensor/tmp105: Convert printf() to trace event, add tracing for read/write access

printf() unconditionally prints to the console which disturbs `-serial stdio`.
Fix that by converting into a trace event. While at it, add some tracing for
read and write access.

hw/sensor/tmp105: Lower 4 bit of limit registers are always 0

Per datasheet, "HIGH AND LOW LIMIT REGISTERS", the lower 4 bit
of the limit registers are unused and always report 0.
The lower 4 bit should not be used for temperature comparisons,
so mask the unused bits before storing the limits.

Clear the ONE_SHOT bit in the WRITE path. Now than the READ path is
simpler, we can also simplify tmp105_alarm_update().

hw, target: Add ResetType argument to hold and exit phase methods

We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.
