This completes console output cleanup. The remaining calls to
uart_puts() and uart_printf() actually need to be that way.

We can clear the reset cause in system pre-init now because of a
previous change which preserves it across a sysjump.

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

A temperature polling task is added to achieve temporal correction and
also reduce the latency of reading temperature.

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.

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.
