This is to prevent temperature value being read before the first time we
poll sensors causes unexpected error.

TEST="sysjump RW" and then "temps" immediately. Check all temperature
readings are near 300 K.

Each TMP006 temperature sensor has different sensitivity factor. Let's
add a field to set different sensitivity factor for each sensor. Also
update the factors to get more reasonable temperature readings, but
still need more precise calibration.

Additional help messages and usage are gated by
CONFIG_CONSOLE_CMDHELP, so we can turn it on if there's space (adds
about 3KB to image size) and turn it off when there isn't.

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

Currently if ENABLE_VS is off, each time we poll TMP006 sensors, it
takes 1 second for each sensor to return ERROR. Checking for power
before polling help to reduce the time spent on temperature polling.

The debug message is larger than UART transmit buffer so we have to

'tempremote' is a debug command used to assess temperature calculation of
TMP006 sensor. Remove it since we have finished TMP006 module.
Also add back the fixed-point algorithm that is lost in rebasing earlier.
