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.
Fixes: 7e7c5e4c1ba5 "Nokia N800 machine support (ARM)."

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.

Per datasheet, "ONE-SHOT (OS)", the OS bit always returns 0 when reading
the configuration register.
Clear the ONE_SHOT bit in the WRITE path. Now than the READ path is
simpler, we can also simplify tmp105_alarm_update().

The next commit will clear the ONE_SHOT bit in the WRITE
path (to keep the READ path trivial). As a preliminary step,
pass the 'oneshot' value as argument to tmp105_alarm_update().
No logical change intended.

To improve readability, use the registerfields API.
Define the register bits with FIELD(), and use the
FIELD_EX8() and FIELD_DP8() macros. Remove the
abbreviations in comments.

Coding style asks for no space between variable and "++". The next patch
in this series will change one of those assignments. Instead of changing
just one with that patch, change all of them for consistency.
While at it, also fix other coding style problems reported by checkpatch.

Lots of this are expected to be coming in, create a directory for them.
Also move the tmp105.h file into the include directory where it
should be.
