Create new inv_sensors common modules and move inv_icm42600
timestamp module inside. This module will be used by IMUs and
also in the future by other chips.
Modify inv_icm42600 driver to use timestamp module and do some
headers cleanup.

Add a timestamping mechanism for buffer that provides accurate
event timestamps when using watermark. This mechanism estimates
device internal clock by comparing FIFO interrupts delta time and
device elapsed time computed by parsing FIFO data.
Take interrupt timestamp in hard irq handler and add IIO device
specific timestamp structures in device private allocation.

Add all FIFO parsing and reading functions. Add accel and gyro
kfifo buffer and FIFO data parsing. Use device interrupt for
reading data FIFO and launching accel and gyro parsing.
Support hwfifo watermark by multiplexing gyro and accel settings.
Support hwfifo flush.
