motion: Fix for FIFO support and BMI150

- Compass was not set properly if default config is set to
disable it (frequency == 0). We were trying to set it up
while stuck in debug mode.
- BMI150 FIFO collects sensor info even when suspended.
Ask FIFO to ommit suspended sensors.
- FIx compliation issue on nucleo-f411 board, where
MKBP is not enabled.
- Fix location of __packed arguement.

BRANCH=smaug
BUG=none
TEST=Check the compass is back with accelinfo,
FIFO is not filled with garbage with fiforead.
Check by echoing in in_accel_z_calibbias that the format
of MOTIONSENSE_CMD_SENSOR_OFFSET has not changed.
