Add a task to update temperature values in LPC mapped value space every
second. Also modify ectool to read directly from LPC mapped space.

TEST="ectool temps" gives same result as "temps" from ec console.

A temperature polling task is added to achieve temporal correction and
also reduce the latency of reading temperature.
Factor out sensor specific part to keep code clean.

TEST=On link, 'temps' shows all temperature readings.
Cover each sensor with hand and see object temperature rise.
Compilation succeeded on bds/adv/daisy/discovery.

We prefer to use floating-point version but we might need fixed-point
version in the future if we don't have FPU support. If CONFIG_FPU flag
is not set, fixed-point object temperature calculation would be used.

The temperature calculation currently uses fixed point operations.
Change it to use floating point for better readability and maintenance.
Also changes disable_fpu() to accept parameter which serves as
optimization barrier to prevent floating point operations after
disabling FPU.

TEST=In console, tempremote "tempremote 29715 -105000 6390" gives 28506.

Currently, 'tempsinfo' command would abort when encountering problems
reading temperature sensor info. Change this command to continue reading
succeeding sensors.
Also change 'temps' to show temperature in both 'K' and 'C' for better
reading and easier debugging.

Remove id field from temp_sensor_t struct, since it's only used by the
console command (which already knows the id, because it's looping over
it).

command to calculate temperature with manually entered data.

Refactor board/chip-specific code into corresponding directories.
Add support of the four I2C temp sensor in Link.
Use table lookup to handle different types of temperature sensors.
