- minor scheduling improvements
- if expected number of samples larger than expected adjust timestamp sample and save sample for next iteration
- when scheduling via data ready interrupt (with no FIFO watermark) count continuously without clearing
- track consecutive failures and trigger reset aggressively
- only count missed drdy interrupts, not time
- reset wait times consistent with other drivers
- accel improve FIFO count check if DRDY isn't available
- track consecutive failures and trigger reset aggressively
- only count missed drdy interrupts, not time
- reset wait times consistent with other drivers
- the latch would actually cause more problems if the backup schedule hit
- this reduces the number of cycles where the FIFO is actually empty at max rate (when there's only 1 sample in the FIFO expected)
- remove all remaining IOCTLs for accel and gyro and handle all calibration entirely in sensors module with parameters
- sensor_accel and sensor_gyro are now always raw sensor data
- calibration procedures no longer need to first clear existing values before starting
- temperature calibration (TC) remove all scale (SCL) parameters
- gyro and baro scale are completely unused
- regular accel calibration scale can be used (CAL_ACC*_xSCALE) instead of TC scale
- accel & gyro FIFOs enabled
- FIFO watermark on data ready interrupt
- sensor side filtering completely disabled
- gyro now respects `IMU_GYRO_RATEMAX` (up to 2 kHz)
- saves a few % cpu (at default rate)
