LSM6: Correct timestamp reporting and FIFO length
When an accelerometer sends a sample to the motion_sense task with a
timestamp, the timestamp should represent the time of the IRQ which
caused the FIFO read. This change caches a timestamp after the
accelerometer data is read to use when pushing all data from that read.
This also corrects the number of bits in the FIFO length field.
